It would seem that what could be simpler than a unit of measures to which every person faces literally from the cradle.Meter, kilogram, liter ... However, sometimes life raises new questions even before these "gurus".One of such examples - it is a meter.Indeed, the lessons of school geometry in terms of any such values are not measured.So, maybe they do not exist, and themselves running meters - pure fiction?Now that the Internet is accessible to all, in theory, you can easily find the answer to almost any question.The main thing - it is right to formulate it.An inquisitive user has typed in the search bar of your browser request "that the meter is" certainly surprised the fact that these words are combined with the kitchen theme.What does this mean?
Standard
Perhaps, after all, is a detailed look into the question of what a meter.Obviously, since we are talking about units of measurement, the search for the answer should be in France, in the Bureau of Weights and Measures, where all reference samples SI.But if we could look at the stands, no mythical linear meter was not found.This indicates that the present meter the required measure of length is only indirectly related.
originally as a reference was taken one ten-millionth part of the length of the terrestrial meridian that intersects with Paris.The necessary measurements were made in 1795, and after making corrective amendments, in 1799, on the basis of the data line is made of stainless platinum size.Subsequently, however, the accuracy of the meter is increasingly questioned, since the shape of the planet is far from a perfect sphere, and in classic geodesy obtain such unprecedented accuracy without satellite metric is almost impossible.If at the time of the original "standard" his accuracy was quite sufficient for all the tasks of the time, that every year the situation changed.As a result, in 1960, it was proposed to use as the meters some fraction of the wavelength of the atomic transition in krypton.And only 23 years later he received the standard of their modern interpretation, tied to the length of the path of a light beam in a vacuum.
What is a meter?
This term is used primarily in the sale of rolled materials.Through it manages to greatly simplify the calculations.For example, a person needs to buy 10 square meters of linoleum.The outlets active material sold in rolls, the width of which is invariable for each model.Thus, to obtain the required 10 sq.m for the roll width of 2 m, it is necessary to measure just 5 m. Since m 2 * 5 = 10 square meters.m. Here are the 5 - and there are meter.In other words, the meter is equal to the reference value, but in view of any further constant value (in this case the width).
However, this definition requires some explanation, as the frequent expression "linear meter kitchen," is not always clear.After all, by analogy, with the purchase of kitchen units, theoretically, can be asked to unwind from the roll a certain number of cabinets.The confusion arises from the fact that sellers of such furniture products previously mentioned constant values are considered not wide, and the cost of material and labor.If we know the price of a meter, and each subsequent differs only spatial configuration (while maintaining the same amount of materials), it can be much easier to use the concept of indicative calculations per meter.Buyers interested in the value "of the model is the same kitchen, but greater or lesser length," can easily calculate it, even on their own.
