# Cambodian units of measurement

A number of units of measurement were used in Cambodia to measure length, mass, capacity, etc. Since 1914, the metric system is compulsory in Cambodia.[1][2]

## System before metric system

### Length

Several units were used to measure length. One muoi (or mot thuoc) was equal to 1 metre.[3] Some other units are given below:.[3]

1 phyeam = 2 muoi = 2 m

1 sen = 20 phyeam = 40 muoi = 40 m

1 yoch = 400 sen = 16,000 muoi = 16 km

### Weight

Several units were used to measure mass. One muoi (mot dong can tay) was equal to 0.600 kg.[3] Some other units are given below:[3]

1 lin = ^{3}⁄_{80} muoi = 22.5 g

1 hun = 10 lin = ^{3}⁄_{8} muoi = 225 g

1 chin = 10 hun = 3 ^{3}⁄_{4} muoi = 2.25 kg

1 tael = 10 chin = 37 ^{1}⁄_{2} muoi = 22.5 kg

1 neal = 16 tael = 600 muoi = 360 kg

1 pram roi (not can tay) = 1000 muoi = 600 kg

1 chong = 50 neal = 30,000 muoi = 18 t

1 hap (picul) = 20 chong = 600,000 muoi = 360 t

### Capacity

Several units were used to measure capacity. One sesep (vuong mot gia) was equal to 40 litres.[3] Some other units are given below:[3]

1 muoi (vuong mot ba tay) = ^{1}⁄_{40} sesep = 1 l

1 kantang = ^{3}⁄_{16} sesep = 7.5 l

1 tao = 2 kantang = ^{3}⁄_{8} sesep = 15 l

1 thang = 2 tao = ^{3}⁄_{4} sesep = 30 l

## Metric system

### Length

Metric system has been compulsory with the name muoi mètre for meter.[1]

### Mass

Metric system has been compulsory with the following names:[1]

1 muoi gramme = 1 g

1 hocsep = 60 kg.
