Everything is measurable. It is a fact. But the quantities used are different. Most of the products that are rolled into a roll, which are related to fittings and kitchen products, are measured in running meters today. More precisely, a running meter is how many meters in length. Width is not included.

In one store, these stripes are in this form and lie. But in another there is just one wide strip of 3 meters, 10 meters long. In fact, this is what we need. Since the cost is indicated in running meters, we will pay three times more in the first store than in the second. The savings are huge!

Remember, 1 running meter is 1 meter long. And then it doesn't matter what width. The price will not change anymore.

Caution!

Very often, only the number of running meters and the price are indicated in the product information card. This means that we do not know anything about the width of the product. If you buy everything in a store or a bazaar, you can come with your own tape measure.

Such data is often hidden on the Internet. You cannot order a product without making sure its parameters. It is worth calling the store and finding out its width.

Having found two identical items with different prices, do not rush to order a cheap one. It is possible that the width of those products will not suit you.

The marking of the fabric is a matter, although not simple, but accurate. With kitchens, which are also measured in linear meters, everything is much more complicated. Usually, we take into account 1 meter of a standard headset. That is, simple cabinets and tables are always used for miscalculations. All additional decorative elements are negotiated separately.

If you are buying a ready-made kitchen, then information about running meters is not particularly important. You already see the finished price tag and decide if the price is right or not. But with individual orders everything must be carefully considered.

It is important to emphasize that you can never know in advance exact amount... We can only judge the minimum cost of 1 running meter of your future kitchen.

There are two popular situations in which the answers are completely different:

1. Accurate calculation. You order an ordinary kitchen, where all drawers, cabinets and tables have standard sizes... You don't change anything. The final price may differ slightly from the planned one.

2. Completely inaccurate calculation. The kitchen is completely original. All cabinets and drawers are designed for your convenience and size of dishes and furniture. The headset fits perfectly into the design of the room. The final price can be several times higher.

Why the total is growing

It is difficult to translate running meters. And for the sake of a new idea, you have to put up with the pricing policy. To cut costs, it is worth combining different components. That is, it is necessary to use as many standard elements as possible, diluting them with custom ones. This way you get a kitchen that fits well into the interior and save your budget.

Do not forget that different materials and designer things increase the cost. One running meter of a locker can become more expensive if you decide to install not 4, but 5 drawers in it. Each detail requires additional expenses. Carvings or decorative stickers are far from cheap.

Alternative to running meter

Many stores calculate prices based on ready-made kitchens. You choose the model you like, see its price, and then change it a little, if necessary. In such cases, it is easier to estimate a future purchase.

As a result, we see that a running meter is a quantity by which many goods are measured, from fabric to kitchen. It specifies the length without specifying the width. In order not to make a mistake in buying, you need to clarify all the points. If on the Internet they refuse to tell you the width, then you should not risk it. After all, you can simply lose your money.

Almost every person must have heard the expression "running meter". For many, this definition remains quite difficult, since it is completely unclear what is the difference between sq. m. from ordinary. What is the conversation going on?

One running meter is equal to the usual length of one meter.It is used to measure goods that have a specific width, such as linoleum. It is much easier to calculate the cost of goods, taking running meters as a basis, than to calculate the cost per square meter.

For example, you need to purchase a carpet in the store, 2.5 wide and a certain length. To make a calculation of 1 m2, such a segment is not very convenient. To do this, you need to determine the area of \u200b\u200bthe product. Then divide it into squares. In other words, you need to perform difficult mathematical calculations.

It is much easier to carry out calculations on the basis of a linear one. To determine the cost of the goods, you will need to multiply the length of the carpet segment by the number of meters.

There is a fairly large list of goods in which the cost is calculated by the number of running meters. These include.

• Fabrics.
• Linoleum.
• Carpet.
• Finishing film.
• Rolled polyethylene.
• Electric wires.
• All kinds of pipes.
• Various fences.
• Fences.

Furniture calculation

A lot of consumers believe that the calculation in linear meters applies only to roll materials. However, this opinion is not entirely true. When buying a product, we often come across a certain roll width. The cost of the furniture is often determined by the runners.

To make it clear, let's turn to the next example.

The furniture manufacturer has made a rough estimate. To completely fill a three-meter kitchen, taking into account all the furniture details, he will need 30,000 rubles. Therefore, the cost of 1 m of furniture will be 10,000 rubles. In other words, this cost will correspond to the price of one running meter. Based on such, fairly simple mathematical calculations, the furniture manufacturer can inform the customer what the cost of a set of furniture of the corresponding sample will be.

However, it is necessary to take into account one important nuance. When calculating the price r. m, only the cost of the cheapest fittings and material was taken into account. Sometimes the cost of fittings is not included in the calculation at all.

Therefore, if a very tempting offer is made to you, it is imperative to find out what material the product is made of, what fittings are installed on it. In this way, new customers are often attracted.

How many mm in running meter

As already mentioned, one running meter is equal to one standard meter. Hence it turns out that 1 running meter is 1000 mm.

Cheat sheet

So, to make it easier to understand the units of measurement, they can be summarized in one table, in which their ratio will be seen, and it will be quite easy to transfer one unit to another.

What does the term "square meter" mean?

This unit is intended for calculating the area of \u200b\u200ba square, each side of which will be 1 meter. To determine the size of the area, you need to multiply the height and length of the product. The short form is used for designation - sq. m.

Today this unit is found almost everywhere in our life. The most obvious example is the size of the living space. In other words, if we are talking about an apartment of 16 m2, then the floor area is equal to this value.

The square meter is most commonly found in the construction industry. To determine the area of \u200b\u200ba wall that is 6 m long and 4 m high, you just need to multiply six by four. It turns out that the wall area is 24 m2.

More about length and distance

General information

Length is the longest measurement of the body. In 3D space, length is usually measured horizontally.

Distance is a value that determines how far two bodies are from each other.

Distance and length measurement

Distance and length units

In SI, length is measured in meters. Derived quantities such as kilometer (1000 meters) and centimeter (1/100 meter) are also commonly used in the metric system. In countries that do not use the metric system, such as the United States and Great Britain, units such as inches, feet and miles are used.

Distance in physics and biology

In biology and physics, lengths are often measured much less than one millimeter. For this, a special value is adopted, a micrometer. One micrometer is equal to 1 × 10⁻⁶ meters. In biology, micrometers measure the size of microorganisms and cells, and in physics, the length of infrared electromagnetic radiation. The micrometer is also called the micron and is sometimes, especially in the English-language literature, denoted by the Greek letter µ. Other derivatives of the meter are also widely used: nanometers (1 × 10⁻⁹ meters), picometers (1 × 10⁻¹² meters), femtometers (1 × 10⁻¹⁵ meters and attometers (1 × 10⁻¹⁸ meters).

Navigation distance

In shipping, nautical miles are used. One nautical mile is equal to 1852 meters. It was originally measured as an arc of one minute along the meridian, that is, 1 / (60 × 180) meridian. This made it easier to calculate latitude, since 60 nautical miles equals one degree of latitude. When distance is measured in nautical miles, speed is often measured in nautical knots. One nautical knot is equal to the speed of one nautical mile per hour.

Distance in astronomy

In astronomy, long distances are measured, so special quantities are adopted to facilitate calculations.

Astronomical unit (a. e., au) is equal to 149,597,870,700 meters. The magnitude of one astronomical unit is a constant, that is, a constant value. It is generally accepted that the Earth is at a distance of one astronomical unit from the Sun.

Light year is equal to 10,000,000,000,000 or 10¹³ kilometers. This is the distance that light travels in a vacuum in one Julian year. This value is used in popular science literature more often than in physics and astronomy.

Parsec approximately equal to 30,856,775,814,671,900 meters or approximately 3.09 × 10¹³ kilometers. One parsec is the distance from the Sun to another astronomical object, such as a planet, star, moon, or asteroid, at an angle of one arc second. One arc second is 1/3600 of a degree, or approximately 4.8481368 mrad in radians. Parsec can be calculated using parallax - the effect of a visible change in body position, depending on the point of view. During measurements, a segment E1A2 (in the illustration) is laid from the Earth (point E1) to a star or other astronomical object (point A2). Six months later, when the Sun is on the other side of the Earth, a new segment E2A1 is laid from the new position of the Earth (point E2) to a new position in space of the same astronomical object (point A1). In this case, the Sun will be at the intersection of these two segments, at point S. The length of each of the segments E1S and E2S is equal to one astronomical unit. If we put a segment through point S, perpendicular to E1E2, it will pass through the point of intersection of segments E1A2 and E2A1, I. The distance from the Sun to point I is segment SI, it is equal to one parsec when the angle between segments A1I and A2I is two arc seconds.

On the picture:

• A1, A2: apparent position of the star
• E1, E2: Earth position
• S: position of the sun
• I: intersection point
• IS \u003d 1 parsec
• ∠P or ∠XIA2: parallax angle
• ∠P \u003d 1 arc second

Other units

League is an obsolete unit of length previously used in many countries. It is still used in some places, such as in the Yucatan Peninsula and in rural Mexico. This is the distance that a person travels in an hour. Nautical League - three nautical miles, approximately 5.6 kilometers. Lie is a unit roughly equal to a league. IN english language both leagues and leagues are called the same, league. In literature, le is sometimes found in the titles of books, such as "20,000 Leagues Under the Sea" - the famous novel by Jules Verne.

Elbow - the old value, equal to the distance from the tip of the middle finger to the elbow. This value was widespread in the ancient world, in the Middle Ages, and until modern times.

Yard used in the British imperial system of measures and is equal to three feet or 0.9144 meters. In some countries, such as Canada, where the metric system is adopted, yards are used to measure the fabric and length of swimming pools and sports fields and fields such as golf and soccer.

Definition of meter

The definition of the meter has changed several times. The meter was originally defined as 1 / 10,000,000 of the distance from the North Pole to the equator. Later, the meter was equal to the length of the platinum-iridium standard. Later, the meter was equated to the wavelength of the orange line of the electromagnetic spectrum of the krypton atom ⁸⁶Kr in vacuum, multiplied by 1,650,763.73. Today, the meter is defined as the distance traveled by light in a vacuum in 1/299 792 458 seconds.

Calculations

In geometry, the distance between two points, A and B, with coordinates A (x₁, y₁) and B (x₂, y₂) is calculated by the formula:

The sun is the source of life on the planet. Its rays provide the necessary light and warmth. At the same time, the ultraviolet radiation of the Sun is detrimental to all living things. To find a compromise between useful and harmful properties Sun, meteorologists calculate the index of ultraviolet radiation, which characterizes the degree of its danger.

What UV radiation from the Sun is

Ultraviolet radiation from the Sun has a wide range and is divided into three regions, two of which reach the Earth.

• UV-A. Long-wave range radiation
  315-400 nm

  The rays pass almost freely through all atmospheric "barriers" and reach the Earth.

• UV-B. Medium wavelength range
  280-315 nm

  The rays are 90% absorbed by the ozone layer, carbon dioxide and water vapor.

• UV-C. Shortwave range radiation
  100-280 nm

  The most dangerous area. They are completely absorbed by stratospheric ozone before reaching the Earth.

The more ozone, clouds and aerosols in the atmosphere, the less the harmful effects of the Sun. However, these saving factors have a high natural variability. The annual maximum of stratospheric ozone occurs in the spring, and the minimum in autumn. Cloudiness is one of the most variable characteristics of weather. Carbon dioxide content also changes all the time.

At what values \u200b\u200bof the UV index is there a danger

The UV Index gives an estimate of the amount of UV radiation from the Sun on the Earth's surface. UV Index values \u200b\u200brange from safe 0 to extreme 11+.

• 0 - 2 Low
• 3 - 5 Moderate
• 6 - 7 High
• 8 - 10 Very high
• 11+ Extreme

At mid-latitudes, the UV index approaches unsafe values \u200b\u200b(6–7) only at the maximum height of the Sun above the horizon (occurs in late June - early July). At the equator, the UV index reaches 9 ... 11+ points throughout the year.

Why the sun is useful

In small doses, the sun's UV radiation is essential. The sun's rays synthesize melanin, serotonin, vitamin D necessary for our health, and prevent rickets.

Melanin creates a kind of protective barrier for skin cells from the harmful effects of the sun. Because of it, our skin darkens and becomes more elastic.

The hormone of happiness serotonin affects our well-being: it improves mood and increases overall vitality.

Vitamin D strengthens the immune system, stabilizes blood pressure and has antirachitic functions.

Why the sun is dangerous

Taking sun baths, it is important to understand that the line between beneficial and harmful Sun is very thin. Excessive tanning always borders on a burn. Ultraviolet radiation damages DNA in skin cells.

The body's defense system cannot cope with such an aggressive effect. It lowers immunity, damages the retina, causes skin aging and can lead to cancer.

Ultraviolet light destroys the DNA chain

How the sun affects people

Susceptibility to UV radiation depends on skin type. People of the European race are most sensitive to the Sun - for them protection is required already at index 3, and 6 is considered dangerous.

At the same time, for Indonesians and African Americans, this threshold is 6 and 8, respectively.

Who is most affected by the Sun

People with light
skin tone

People with many moles

Mid-latitude residents on holiday in the south

Winter lovers
fishing

Alpine skiers and climbers

People with a family history of skin cancer

In what weather is the sun more dangerous

It is a common misconception that the Sun is dangerous only in hot and clear weather. You can get burned in cool, cloudy weather.

Cloudiness, no matter how dense it may be, does not at all reduce the amount of ultraviolet radiation to zero. In mid-latitudes, cloudiness significantly reduces the risk of sunburn, which cannot be said about traditional places. beach holiday... For example, in the tropics, if in sunny weather you can get sunburned in 30 minutes, then in cloudy weather - in a couple of hours.

How to protect yourself from the sun

To protect against harmful rays, observe simple rules:

Stay less in the Sun at noon hours

Wear light colored clothing, including wide brimmed hats

Use protective creams

Wear sunglasses

More shade on the beach

Which sunscreen to choose

Sunscreen varies in sun protection and is labeled from 2 to 50+. The numbers indicate the proportion of solar radiation that overcomes the protection of the cream and reaches the skin.

For example, when applying a cream labeled 15, only 1/15 (or 7%) of the UV rays will penetrate the protective film. In the case of cream 50 - only 1/50, or 2%, affect the skin.

Sunscreen creates a reflective layer on the body. At the same time, it is important to understand that no cream can reflect 100% of ultraviolet radiation.

For everyday use, when the time spent under the sun does not exceed half an hour, a cream with protection 15 is quite suitable. For sunbathing on the beach, it is better to take 30 or more. However, for fair-skinned people, it is recommended to use a cream labeled 50+.

How to apply sunscreen

The cream should be applied evenly to all exposed skin, including the face, ears and neck. If you plan to sunbathe long enough, then the cream should be applied twice: 30 minutes before going out and, additionally, before going to the beach.

Specify the required amount for application in the instructions of the cream.

How to apply sunscreen when swimming

Sunscreen should be applied every time you bathe. The water washes away the protective film and reflects sun rays, increases the dose of received ultraviolet radiation. Thus, when bathing, the risk of sunburn increases. However, due to the cooling effect, you may not feel the burn.

Excessive sweating and towel drying is also a reason to re-protect your skin.

It should be remembered that on the beach, even under an umbrella, the shade does not provide adequate protection. Sand, water and even grass reflect up to 20% of UV rays, increasing their effect on the skin.

How to protect your eyes

Sunlight bouncing off water, snow or sand can cause painful retinal burns. Use UV-filtered sunglasses to protect your eyes.

Danger to skiers and climbers

In the mountains, the atmospheric filter is thinner. For every 100 meters of altitude, the UV index increases by 5%.

Snow reflects up to 85% of UV rays. In addition, up to 80% of the ultraviolet reflected by the snow cover is again reflected by the clouds.

Thus, the Sun is most dangerous in the mountains. Protecting your face, lower chin and ears is essential even in cloudy weather.

How to deal with sunburn if you're burned

Sponge your body with a damp sponge to dampen the burn

Apply an anti-burn cream to the burned areas

If the temperature rises, consult a doctor, you may be advised to take an antipyretic

If the burn is severe (the skin is very swollen and blistering), seek medical attention
