The unit of measurement of gold :
If you want to buy gold in the international market, you can’t buy it in bulk. This is because the international unit of weight measurement, “kilogram” or “ounce”, is used as the unit for selling gold abroad. Fractions of kilograms are “grams”.
So grams or ounces are used more to measure the weight of gold. As, many of us do not know how many grams or ounces are filled. If it is known, gold can be bought easily at home and abroad. At the same time the difference in price is also caught.
- 8 Anna = 5.632 grams
- 14 Anna = 10.206 grams
- 1 Vori = 11.636 grams

Mg is the mass of pure gold in ornaments,
Mm is the total mass of the ornament.
