定义
A yard (symbol: yd) is a length unit in the Imperial and U.S. customary systems. By international agreement in 1959, one yard equals exactly 0.9144 m. It breaks down into 3 feet or 36 inches.

起源
The word “yard” likely comes from the Old English 痛风, meaning “rod” or “staff.” Historical measures varied—sometimes tied to a person’s waist circumference—until mid-20th-century standardization fixed the yard at 0.9144 m.

英寸

定义
An inch (symbol: in) is a customary unit of length in the Imperial and U.S. systems. Since 1959, it has been defined as exactly 25.4 mm. Twelve inches make a foot; 36 inches make a yard.

起源
Tracing back to the Latin 珊瑚虫 (“one-twelfth”), early definitions tied an inch to three barleycorns laid end-to-end or the average width of three thumbs. Modern precision comes from the fixed link to millimeters.
