| 4 tical | = | 1 damling . |
| 20 damling | = | 1 catty ( chang ). |
| 50 catties | = | 1 picul . |
The chang or catty of silver is a double one, hence 50 catties of silver are equal to 100 catties of ordinary commercial weight.
The catty of silver thus weighs 1200 grammes instead of 600 grammes.
They likewise use the moeun of silver = 10 changs = ⅕ picul , but more generally the moeun is used as a measure of capacity which contains 20 catties of shelled rice, but as a measure of capacity it varies and is sometimes equal to 20 catties , sometimes to 25 catties of rice. That it really is a measure of capacity incorporated at a later date into the weight system like our own bushels , barrels and quarters , is made probable by the fact that in the provinces of Tonlé, Ropon, and Melou Préy they employ a tramem or bag containing 10 Cambodian catties , and in the province of Siphoum the moeun is sometimes the name given to a bag or pannier of a cubit in depth, and a cubit in width at the mouth. It is usually called kanchoen ( pannier ),
