In the novel of Mark Twain's "The Adventures of Tom Sawyer," the main character was entrusted to paint the "thirty yards of the wooden fence."

To estimate the amount of work coming hero, Russian reader needs to know the relationship between yards and meters.

Yard - a unit of measurement of length, a member of theEnglish system of measures. It is used not only in the UK but also in the US and other English-speaking countries in particular, the English navy yards calculate the distance by using weapons.
Yard has a certain relationship with the other British measures of length. Yard is 3 feet or 36 inches English.

## History yards

The name of the unit comes from the old Anglo-Saxon word which denotes a straight branch or rod for measuring length.
Yard as a measure of length appeared in the tenth century. It was introduced by the English King Edgar (959-975), defining its value is very simple - based on their own body size. Yard equal to the distance between the tip of the middle finger of the monarch's hands outstretched to the side, and the tip of his nose. On the one hand, it was convenient, but as soon as the new king took the throne, had to change the value of a yard.
The youngest son of William the Conqueror, King HenryI (1068-1135) decided to once and for all put an end to this confusion. He set a fixed length yards. To continue, none of the subjects had any doubts on this score, even the king ordered be made of elm standard. There is a legend that this monarch was a long sword in exactly one yard.
However, despite all the efforts of Henry I, the value of the yard later changed repeatedly.

## Modern yard

Modern standard yard iscompromise the result. In 1959, the state, where applicable, this unit - UK, USA, Australia, New Zealand and Canada - have established so-called "International Yard." Its length is 0.9144 m. Such yard is currently in use. For ease of calculation of its length is often rounded up to 914 cm (0.914 m).
To convert yards to meters, multiplythe number of yards by 0.914. For example, 2 yards - is 1,829 meters (about 1 m 83 cm) and 10 yards - 9.144 m (9 m 14 cm), and the "30 yards of a wooden fence," which was supposed to paint the Tom Sawyer - 27.432 m (approximately 27 m 43 cm). To be more precise calculations can be multiplied and to a more accurate value of the yard - 0.9144, but particularly the practical value of such a clarification would not give.
To perform the reverse operation - convert meters in yards - should be the number of meters divided by 0.914. For example, 20 m - is approximately 21 m 88 cm.
