Summary
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]
System before metric system edit
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]
Length edit
A number of units were used to measure length. One depa was equal to 1.70 m by its legal definition.[2][1] Some other units and their legal equivalents are given below:
1 hasta = 1⁄4 depa
Mass edit
A number of units were used to measure mass.
Ordinary edit
One pikol (or one pecul) was equal to 61.7613025 kg by its legal definition.[2] Some other units and their legal equivalents are given below:
1 thail = 1⁄1600 pikol
1 catti = 1⁄100 pikol
1 kabi = 1⁄100 pikol
1 kulack = 0.0725 pikol
