The kandi = 150 pehthas, about 248.34 kg.

* The great moo/little moo ratio is a puzzle. As the moos are 2 of the respective pais, the ratio between them should be the same as the pais' ratio, which makes the great moo 1 1/3 little moo. But calculating from the documented numbers of kyats in a great moo and little moo makes the great moo 1¼ little moos. For some calculations we have used 1¼ little moo in a great moo, which is required to reach the documented 10 little moo to a kyat, and 5 little pai to a mat.

Doursther describes the moo as a unit for precious metals with 100 moos in a tical, and says that it is 0.15389 grams. Nelkenbrecher says Rangoon has no separate system of weights of precious metals.
