Chinese units of measurement

Japanese units of measurement

Shìzhì ( 市制 ) is the customary and traditional units of measure used in China. In the People's Republic of China, the units were re-standardised during the late 20th century to make them approximate SI (metric) units. Many of the units were formerly based on the number 16 instead of 10. In Hong Kong traditional Chinese units and Imperial units are used alongside the metric system.

Shakkan-hō ( 尺貫法 ) is the traditional Japanese system of measurement. From 1924, the Shakkan-hō system was replaced by the metric system. However, in several instances the old system is still used. In carpentry and agriculture use of the old-fashioned terms is common. Tools such as Japanese chisels, spatels, saws, hammers are manufactured in sizes of sun and bu. Land is sold on the basis of price in tsubo.
