The weights and measures used in the Colony consist of the standards in use in the United Kingdom, and the following Chinese weights and measures, given with their equivalents in avoirdupois:

1 fan (candareen)	=	.0133 ounces
1 ts'in (mace)	=	.133 ounces
1 leung (tael)	=	1.33 ounces
1 kan (catty = 16 taels)	=	1.33 pounds
1 tam (picul = 100 catties)	=	133.33 pounds
	=	1.19 cwts.
	=	0.0595 tons
1 ch'ek (foot)	=	Statutory equivalent 14⅝ inches. The ch'ek is divided into 10 ts'un (inches), and each ts'un into ten fan, or tenths.

In practice the equivalent length of a ch'ek varies, according to the trade in which it is used, from 14⅝ inches to 11½ inches, the commonest equivalent being 14.14 inches.
