How the Tola to Gram Conversion Works
Tola is a unit of mass, and gram is the metric unit of mass. Converting between them needs only one number, the conversion factor.
The factor comes from the definition of the tola itself. The tola is standardised as 180 grains, or exactly 3/8 of a troy ounce. A grain is defined as exactly 64.79891 milligrams, so:
Working through a few examples by hand:
To go the other way, divide the weight in grams by 11.6638038. For example, 50 g ÷ 11.6638038 = 4.2868 tola. Because one gram is about 0.0857 tola, a 10 gram coin is roughly 0.857 tola and not a full tola.

1 Tola Comparison with Other Weight Units
To understand how a single tola compares across modern metric and traditional precious metal systems, the reference table below details what exactly 1 tola equals in grams, troy ounces, masha, ratti, kilograms, milligrams, ounces, and other global bullion standards.
| Target Unit | 1 Tola Equals |
|---|---|
| Grams (g) | 11.6638038 g |
| Troy Ounce (oz t) | 0.3750 oz t |
| Masha | 12 Masha |
| Ratti | 96 Ratti |
| Kilograms (kg) | 0.011664 kg |
| Milligrams (mg) | 11,663.8038 mg |
| Ounces (Avoirdupois oz) | 0.4114 oz |
| Tael (Hong Kong gold tael, 37.429 g) | 0.3116 Tael |
| Troy Grains (gr) | 180 grains |
| Carats (ct) | 58.3190 ct |
The tael differs by region, so the figure depends on which one you use. Against a 37.7994 g Hong Kong or Singapore tael, 1 tola is 0.3086 tael. Against a 37.5 g Taiwan tael, it is 0.3110 tael. Against a 50 g mainland China liang, it is 0.2333 liang.
Hong Kong uses two different values, 37.429 g for gold trading and 37.7994 g as the general legal tael. The 0.3116 figure matches the first.
What Is a Tola?
The tola is a traditional South Asian unit of mass, used mainly to weigh gold and silver. The word is generally traced to the Sanskrit tula, meaning a balance or scale. Before standardisation the weight varied from market to market. The British East India Company fixed it at 180 grains in 1833, matching the weight of its silver rupee, and that value has been carried forward into modern bullion trade.
Because the tola equals exactly 3/8 of a troy ounce, it fits neatly with the unit used by international gold markets. One troy ounce is 31.1034768 g, and 31.1034768 × 3/8 gives the same 11.6638038 g.
What Is a TT Bar (Ten Tola Bar)?
A TT Bar, short for Ten Tola Bar, is a gold bar weighing 10 tolas that is commonly traded in South Asia and the Middle East. In local markets it is also called a tola bar or gold biscuit.

Notes on Regional Practice
Avoid the 10-Gram Shortcut
Some traders informally round 1 tola down to 10 grams for quick mental arithmetic. However, 1 tola is actually 11.6638 grams—about 16.6% heavier. Rounding down to 10 g understates the true weight by ~14% (an 8.319 g loss on a standard 5-tola transaction). When prices are quoted in tola, always divide the gram weight by 11.6638 to verify accuracy.
India Trade Standards
Sections 4 and 11 of the Legal Metrology Act, 2009 require units of weight to follow the metric system and require prices, invoices and other trade documents to state quantity in standard units, which is why jewellery invoices show grams. Exports are exempt. The tola is still common in everyday shop talk, but the gram figure on the bill is the one to rely on.
International Bullion
In India, Pakistan, Bangladesh, Nepal, the UAE and the UK, bullion dealers who sell by the tola work to the same 180-grain weight, 11.6638 g. Many traders round it to 11.664 g in billing, so always check which figure is being used when you compare quotes. For specific local regulations, see our guides on Pakistani Sarafa market conventions, Dubai Gold Souk purchasing guidelines, Nepali bullion trade benchmarks, and British metric hallmarking regulations.
Silver & Other Metals
The tola measures mass, not metal type. 1 tola of silver weighs the exact same 11.6638 g as 1 tola of gold. Purity (karat or fineness) affects price per gram, never the physical weight of the tola.
Tola to Gram Conversion for Gold Prices
Most gold rate boards show a price per gram. To find the price of one tola, multiply by the conversion factor:
For illustration only, assume 24 carat gold is quoted at ₹12,000 per gram. One tola then costs 12,000 × 11.6638038 = ₹1,39,965.65. If the 10 gram shortcut were used instead, the same tola would be priced at ₹1,20,000, a gap of ₹19,965.65. This rate is a round number chosen to show the arithmetic, not a live price.
Keep in mind that the price on a jewellery bill also includes making charges and taxes, and that the gold rate depends on purity. A 22 carat piece, hallmarked as 916, contains 91.6% gold, so its rate per gram is lower than that of 24 carat gold.

Frequently Asked Questions
How many grams are in a tola?
One tola is 11.6638038 grams, usually written as 11.6638 g or 11.664 g. It is defined as 180 troy grains.
Is 1 tola equal to 10 grams?
No. One tola is about 11.66 g, so 10 g is only about 0.857 tola.
Is 1 tola equal to 12 grams?
No. A tola is slightly less than 12 g. The figure 12 is sometimes confused with the 12 masha that make up a tola, which is a different thing.
Why do some sources use 11.664 instead of 11.6638?
11.664 is simply the exact value rounded to three decimal places. The difference is about 0.0002 g per tola, which is too small to affect normal jewellery weighing.
How do I convert tola to grams without a calculator?
Multiply the tola value by 11.66. For quick estimates this is close enough: 4 tola is about 46.6 g. For anything involving money, use the full 11.6638038.
Does the purity of gold change its weight in tola?
No. Weight is independent of purity. A tola of 22 carat gold and a tola of 24 carat gold weigh the same, but they do not cost the same.
Which value should I use for a gold loan or valuation?
Use the gram weight written on the lender's valuation or the hallmarked invoice, since formal documents use grams. Convert to tola only for your own comparison.
How accurate is this converter?
It multiplies by 11.6638038, the exact value derived from the 180 grain definition, and only rounds the displayed result. Always confirm the final weight on a calibrated scale before any transaction.
