often in literature, and in any specialized publications can be found the distance unit - foot.It is customary for us as meters and centimeters?It is difficult to give to this question is an unequivocal answer.The thing is that it (response) depends on which one foot is meant - English, Roman, Russian or Hamburg.
See how many of these values.Generally, each more or less advanced country had its own feet.
To understand why there is such confusion, let's just try to figure out, but what it means, and then we'll figure out how many centimeters in a foot.
So, from the English word translated as foot, everybody knows it.And what is your foot length?You say that the feet are different, and rightly so.But in ancient times, people did not have anything specific on hand to measure.That had to use his own body.The length of it measured in inches (thumb), feet (feet) yards.
with the latter generally came an interesting story.He coined the English King Edgar, who ruled in 959-975 of Albion's.Without further ado, the monarch decided that one yard is equal to the distance from the tip of the nose to the royal middle finger outstretched hand of His Majesty.Will the king - the law, and that the whole country has passed to the new standard.But Edgar was not eternal, and in the next monarch had different proportions.We had to change the measure of length.What we are talking about the yards, in the case before that was about a foot away much meters?So they are very closely linked.In one yard contains exactly 3 feet.In turn, the latter contains a 12-inch.
Why 12 and not 10 familiar to us?After dozens consider how much simpler.Fingers on our hands is 10, and not twelve.
This, of course, is another story, but also not devoid of originality.The fact that 10 only divisible by 2 and 5, besides units and itself, of course.But you can divide the 12 and 2, and 3, and 4, and 6. See the difference?That's why the question of foot - is how many inches you can confidently answer "12".And all these carve-binding and needed only one - for international trade.If merchants brought to London Chinese silk, they sold it to the British feet.When carried in Russian English cloth, they were forced to settle accounts in the Russian measures of length.
A foot - this is how much arshins or yards?And it should be measured.
Today, due to the globalized world, almost all countries have long switched to the SI.It resists the major powers only Britain, but it's a bit unify your favorite foot.This is how much was spent effort to draw a parallel between the metric system and the British measures of length?Many, but was it worth it, or it was easier to go to all the SI, a separate issue.
After long debate and numerous measurements are now considered to be an international one foot equal to 0.3048 m. If you need to know the length of a yard, then simply multiply this number by three.
If you take shoe sizes, the length of the foot of one foot corresponds to about 45.5 Russian size and 47 European.
