ts'un

See also ts'un and cun.

In China, a unit of length equal to 1.41 inches, one of the so-called “treaty standards,” whose values were set by a series of treaties (1842–1844 and 1858–1860) imposed on China by Britain and France, and used thereafter by the Chinese maritime customs (though not elsewhere in the country). “Ts'un” is the romanization (Wade-Giles) usually used by English-speaking Europeans at that time.
