About these units

Inch (in)

US & ImperialCurrent unit

1/12 of a foot. Defined as exactly 25.4 millimeters since 1959, when the US and Commonwealth countries agreed a common international inch.

Latin uncia, meaning one-twelfth, is the root of both inch and ounce, and it passed into Old English as ynce. Roman measurers divided their foot into twelve unciae, and the English inch kept that twelfth. After 1066 an inch was reckoned as three barleycorns, and a 1324 statute attributed to Edward II spelled out the definition as three grains of barley, dry and round, placed end to end lengthwise. For centuries the inch was simply a twelfth of a foot, or a thirty-sixth of a yard, and the US and UK each kept their own copy of the standard yard.

Those copies differed slightly until the 1959 international agreement fixed the yard at exactly 0.9144 meter, which made the inch exactly 25.4 millimeters. The US adopted it in 1959 and the UK ratified it in 1963, effective 1964. Today the inch is still the customary unit in the United States and Canada, and the UK keeps it on road signs. Worldwide it also names display diagonals, wheel rims, tire codes and pipe sizes.

1 inch = 0.0254 meters (exactly).

Zhang (Chinese) (zhang)

ChineseTraditional unit (still used in some regions)

Ten chi, 10/3 m (about 3.33 m) in the modern market system.

Ten chi made one zhang, so the unit was always a measure of the human scale of buildings and cloth rather than of personal reach. It turns up in Chinese architecture as a way to describe the width of a bay and the height of walls and pillars. Since the chi itself changed from dynasty to dynasty, the zhang changed in step with it and had no independent standard.

Republican law fixed it twice. In 1915 the Republic of China set it at about 3.2 m, and in 1930 the figure was revised to exactly 10/3 m, about 3.33 m, which is the value used here. Mainland China uses it rarely today, and everyday speech tends toward meters. The Japanese jo is built the same way from ten shaku, giving about 3.03 m, which shows how a shared structure produced different lengths.

1 zhang (Chinese) = 3.333333333 meters (approximately).
