These are based on the Tolchah, the Máshah, and the Surkh.
Formerly 6 now | 7½ rice-grains | = 1 Surkh |
8 Surkh | = 1 Máshah | |
12 Máshah | = 1 Tólchah. |
The ordinary weights in use are ½, 1, and 4 Surkh: 1, 2, 4, 6, Máshah: 1, 2, 5, 10, 20, 50, 100, 200, 500 Tólchah. But in the imperial Exchequer, the gradations of weight kept ready are very numerous.
