1 lin = muoi = 22.5 g
1 hun = 10 lin = muoi = 225 g

1 tael = 10 chin = 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. Some other units are given below:
1 muoi (vuong mot ba tay) = sesep = 1 l
1 kantang = sesep = 7.5 l
1 tao = 2 kantang = sesep = 15 l
1 thang = 2 tao = sesep = 30 l
