Gold is weighed in different units depending on where you are: grams in most shops, tolas in the Gulf and South Asia, and troy ounces on global markets. This guide makes gold weight conversion simple.
The key numbers
- 1 tola = 11.664 grams
- 1 troy ounce = 31.1035 grams
- 1 kilogram = 1,000 grams
Note that a troy ounce, used for precious metals, is heavier than the ordinary ounce (28.35 g) used for food.
Reference table
- 1 gram = 0.0857 tola = 0.0322 troy oz
- 10 grams = 0.857 tola = 0.322 troy oz
- 1 tola = 11.664 g = 0.375 troy oz
- 10 tola bar = 116.64 g = 3.75 troy oz
- 1 troy oz = 31.1035 g = 2.667 tola
- 1 kilo bar = 32.15 troy oz = 85.74 tola
Converting prices
Because prices follow the same units, you can convert them the same way:
- Price per tola = price per gram × 11.664
- Price per gram = price per ounce ÷ 31.1035 (then × 3.6725 to convert dollars to dirhams)
- Price per kilo = price per gram × 1,000
Example: if 24K gold is 450 dirhams per gram, a 24K tola is 450 × 11.664 = 5,248.80 dirhams, and a 10-tola bar is about 52,488 dirhams.
Our site shows the tola price in the main table, and the gold calculator accepts weights in grams, tolas or ounces.
Common bar sizes in the UAE
- 1 g, 2.5 g, 5 g, 10 g, 20 g and 50 g small bars
- 1 tola and 10 tola bars, very popular locally
- 1 troy ounce bars and coins
- 100 g and 1 kg bars for larger investors
Small bars usually carry a higher premium per gram than large bars.
