The Indian standard tola is 11.66 grams (exactly 11.6638 g). Many jewellers today also call 10 grams a tola, so check the weight in grams when you buy gold.

1 tola = 12 masha and 1 masha = 8 ratti, so 1 tola has 96 ratti. That makes 1 ratti about 0.12 grams.

A standard maund (man) is 40 ser, and 1 ser is 80 tola. So 1 maund is about 37.3 kg and 1 ser about 933 grams. In the past these values also varied a little from region to region.

Gold and silver prices are set worldwide in troy ounces. 1 troy ounce = 31.10 grams, a little heavier than the ordinary ounce (28.35 grams).
