The base unit of length in the imperial system. Its symbol is yd. It is defined as 0.9144 meters. It originated from the double cubit of the ancient Orient, but the name is said to come from the girdle. One yard is equal to 3 feet (36 inches). There are many legends about its origin, including one that it was the length from the tip of Henry I's nose to the tip of his thumb, and another that it was the length of the Anglo-Saxon waist. A standard scale was created during the reign of Elizabeth I, and a new prototype, the Imperial Standard Yard, was created in 1855. However, there were some differences between the United States and Commonwealth countries, so 0.9144 meters was decided as the scientific agreement value between the countries in 1958, and was adopted by the British Standards Institution in 1963.

ヤード・ポンド法の長さの基本単位。記号はyd。0.9144メートルと定義されている。起源は古代オリエントのダブルキュービットだが、名称は腰帯(ガードル)に由来するらしい。1ヤードは、3フィート(36インチ)にあたる。起源の伝説は多く、ヘンリー1世の鼻の先から前に突き出した手の親指の先までとか、アングロ・サクソンの腰まわりの長さとかいう説がある。エリザベス1世のとき標準尺がつくられて安定し、1855年に新しい原器、帝国標準ヤードがつくられた。しかし、アメリカやイギリス連邦諸国との間で多少の差が生じていたので、1958年各国間の科学用協定値として0.9144メートルが決まり、1963年イギリス規格協会も採用した。 [小泉袈裟勝] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
