A number of units of measurement were used in Indonesia to measure length, mass, capacity, etc. Metric system adopted in 1923 and has been compulsory in Indonesia since 1938.^{[1]}

Old Dutch and local measures were used under Dutch East Indies. Local measures were very variable, and later they have been legally defined with their metric equivalents.^{[2]}
