Convert yards to feet

庭院

定义
A yard (symbol: yd) is a length unit used in both the Imperial and U.S. customary systems. Since 1959, it has been precisely defined as 0.9144 meters. One yard equals 3 feet or 36 inches.

起源
The term “yard” likely comes from the Old English word 痛风, meaning “rod” or “measure.” In medieval England, various “yard” lengths coexisted—sometimes based on the girth of a person’s waist—until an international agreement in 1959 standardized it at exactly 0.9144 m.

现代使用
Yards are the go-to unit for sports field layouts (American & Canadian football, soccer, cricket pitches), and they’re commonly used in everyday distance references in the U.K. and U.S. In Britain, short-distance road signs still must display yards alongside metric units.

脚

定义
A foot (symbol: ft) is a customary length unit in the Imperial and U.S. systems, defined since 1959 as exactly 0.3048 meters. Each foot comprises 12 inches, and three feet make one yard.

起源
Historically, many cultures—from the Greeks and Romans to medieval Europeans and Asians—used body-based “foot” measures that ranged between roughly 250 mm and 335 mm. The 1959 international agreement unified these variations into the modern 0.3048 m foot.

现代使用
Feet remain standard in the United States, Canada, and the United Kingdom for measuring personal height, room dimensions, field lengths, and aviation altitudes. They coexist with metric units in scientific and industrial contexts.
