About these units

Mu (Chinese) (mu)

ChineseTraditional unit (still used in some regions)

Exactly 10,000/15 m² (666.67 m²), one fifteenth of a hectare. The standard unit of farmland in China.

A mu was once a plot defined by a square count of bu, the double pace used as a surveying step. Han-era writers recalled that in earlier times 100 square bu made a mu, while in their own day 240 were needed, and calculations from Han rulers give a mu of roughly 461 m². The size kept shifting. The 1915 Beiyang government law defined it as 60 square zhang, about 614.4 m².

The Republic's 1930 market system settled on 1/15 of a hectare, which is the 666.67 m² used here, and the mu is the only traditional Chinese area unit that survived the 1959 State Council decree. Farmland statistics in China are still given in mu, so that 15 mu make one hectare and 1,500 mu a square kilometre. Hong Kong and Macau use a mou of about 761.4 m², while Taiwan and Japan use a unit of about 99.17 m². The idiom of one mu and three fen of land describes a person's small personal patch.

1 mu (Chinese) = 666.6666667 square meters (approximately).

Square Inch (in²)

US & ImperialCurrent unit

A square one inch on a side, exactly 6.4516 cm². Used for small parts and for pressure (pounds per square inch).

Latin uncia, one twelfth, gave English the inch, which Old English borrowed as ynce. A statute of Edward II in 1324 defined it as three barleycorns, dry and round, set end to end, and the barleycorn remained the base for centuries after 1066. The modern square inch rests on a 20th-century agreement: the United States adopted a yard of exactly 0.9144 meter on 1 July 1959, the United Kingdom followed effective 1 January 1964, and the inch became exactly 25.4 mm.

Squaring that gives exactly 6.4516 cm² for one square inch, and one square meter is about 1,550 of them. Its best-known descendant is the pound per square inch, psi, the pressure unit still used for American tires and air tanks: atmospheric pressure at sea level is about 14.7 psi, a car tire is typically inflated to around 32 psi above the surrounding air, and one psi is about 6.895 kilopascals. The square inch itself is common in the US and UK for small parts and printed material.

1 square inch = 0.00064516 square meters (exactly).
