In Mark Twain's novel "The Adventures of Tom Sawyer," the protagonist was instructed to paint "thirty yards of wooden fence."
To assess the amount of work, the upcoming hero, the domestic reader needs to know the relationship between yard and meter.
Yard is a unit of length measurement included inSystem of English measures. It is used not only in the UK, but also in the United States and other English-speaking countries. In particular, in the English fleet in yards calculate distances when using weapons.
The yard has a certain relationship with other English measures of length. The yard is 3 feet or 36 English inches.
The name of this unit of measurement comes from an old Anglo-Saxon word, which denotes a straight branch or rod, designed to measure length.
Yard as a measure of length appeared in the tenth century. He was introduced by the English King Edgar (959-975), determining its magnitude very simply - based on the size of his own body. The yard was equal to the distance between the tip of the middle finger of the monarch, stretched out to the side, and the tip of his nose. On the one hand, it was convenient, but as soon as the throne was occupied by the new king, the size of the yard had to be changed.
The younger son of William the Conqueror, King HenryI (1068-1135) decided once and for all to put an end to such confusion. He set a constant yard length. That henceforth none of the subjects had doubts on this score, the king even ordered to make from the elm a standard. There is a legend that this monarch had a sword of exactly one yard length.
However, despite all the efforts of Henry I, the size of the yard subsequently changed many times.
The modern yard standard is aThe result of a compromise. In 1959, the states where this unit of measure is applied - the United Kingdom, the United States, Australia, New Zealand and Canada - have established the so-called. "International yard". Its length is 0.9144 m. This is the yard currently used. For the convenience of calculations, its length is often rounded to 914 cm (0.914 m).
To convert yards to meters, you must multiplyThe number of yards is at 0.914. For example, 2 yards is 1,829 m (approximately 1 m 83 cm), and 10 yards is 9,144 m (9 m 14 cm), and "30 yards of wooden fence", which Tom Sawyer was supposed to paint - 27,432 m (about 27 m 43 cm). For greater accuracy calculations can be multiplied by a more accurate yard value - 0.9144, but this particular refinement will not give a particular practical value.
To perform the reverse operation - to convert the meters into yards - you need to divide the number of meters by 0,914. For example, 20 m is approximately 21 m 88 cm.
