A masu (?∪?) was originally a square wooden box used to measure rice in Japan during the feudal period. Masu existed in many sizes, typically covering the range from one to (銝??????? ittomasu, c. 18L) to one g? (銝??????? ichig?masu, c. 0.18L).

Dry measures are units of volume used to measure bulk commodities which are not gas or liquid. They are typically used in agriculture, agronomy, and commodity markets to measure grain, dried beans, and dried and fresh fruit (e.g. a peck of apples is a retail unit)
