The half ingot of gold is also used = 8 ingots of silver.
The unit of commercial or avoirdupois weight is the catty (called by the Cambodians the neal) or pound.
| 1 neal (catty) (600 grammes) | = | 16 tomlongs or taels (ounces). |
| 1 tomlong (37·5 grammes) | = | 10 chi (of 3·75 grammes). |
| 1 chi | = | 10 hun. |
The preceding weights are plainly borrowed from the Chinese, whilst the following are regarded as native in origin.
| 1 pey | = | 0·292 grammes. |
| 4 pey | = | 1 fuong (1·174 grammes). |
| 2 fuong | = | 1 slong (2·344 grammes). |
| 4 slong | = | 1 bat (9·375 grammes). |
| 4 bat | = | 1 tomlong (37·5 grammes). |
For heavy merchandise they employ the hap or picul.
There are three varieties of picul: (1) that of the weight of 40 strings of cash (= 100 catties), (2) that of 42 strings, (3) that of 45 strings.
It will be noticed that the first-mentioned is simply the standard of the Chinese picul of 133⅓ lbs. English, whilst the others are native.
In Annam we found that the ingots of gold and silver, consisting of ten luongs or nails, were called nên. The luong was equal in weight to the Chinese liung, and Cambodian tomlong, and was also called dinh (dinh-bac, nail of silver), thus being identical with the ten denh into which the Cambodian nên or bar is divided.
