Gram, Tola and Troy Ounce: Gold Weights Without the Confusion

The world quotes gold in ounces, your local market sells it in tola or bhori, and your invoice is in grams. All three are the same metal.

Same gold, three ways of naming its weight 1 gram 1.000 g 1 tola 11.664 g 1 troy ounce 31.103 g bazaar unit world price unit
One tola is 11.664 g; one troy ounce is 31.103 g.

Nothing about gold confuses new buyers faster than its units. A headline says gold hit a number “per ounce”. The shop quotes you “per bhori”. The receipt says grams. Nobody is cheating you — these are three names for weight, and converting between them is arithmetic.

The only three conversions you need

  • 1 troy ounce — 31.1035 grams. This is the unit the world price is quoted in.
  • 1 tola (bhori) — 11.664 grams. The traditional South Asian unit.
  • 1 ounce — about 2.67 tola. Handy when you compare a global headline to a local rate.

A troy ounce is not a kitchen ounce

The ounce used for gold is the troy ounce: 31.10 g. The ounce used for food is 28.35 g. Using the wrong one puts you off by about 10% — enough to lose a serious amount of money on one purchase.

Turning a world price into a per-gram price

  1. 1 Start with the world price
    Take the quoted price for one troy ounce.
  2. 2 Divide by 31.1035
    That gives you the price of one gram of 24K gold.
  3. 3 Adjust for purity
    For 22K, multiply by 0.916. For 18K, multiply by 0.750.
  4. 4 Add local costs
    Import duty, VAT and the shop’s making charge sit on top.
