Gram to Tola FAQ — Frequently Asked Questions

1 tola is exactly 11.6638038 grams. This value was standardized in 1833 under British colonial administration in India, defined as 180 troy grains. It is the gold standard (literally) for gold measurement across South Asia and the Gulf region. Do not confuse it with the informal 10g approximation used by some jewelers.

To convert grams to tola, use this formula: Tola = Grams ÷ 11.6638038. For example: 50 grams ÷ 11.6638038 = 4.2865 tola. You can also use our Gram to Tola Converter for instant results.

To convert tola to grams, multiply by 11.6638038: Grams = Tola × 11.6638038. Example: 5 tola × 11.6638038 = 58.319 grams. Use our Tola to Gram Converter for quick conversion.

No. 1 tola = 11.6638038 grams. This is one of the most common and costly misconceptions in the gold market. Using 10g as a tola equivalent creates a 14.3% error. For a 10-tola gold purchase, this error equals about 1.66 grams of gold — worth hundreds of dollars at current prices. Always use the precise 11.6638038 figure for financial transactions.

10 grams = 0.8573 tola (precisely 0.857338 tola). Calculation: 10 ÷ 11.6638038 = 0.8573.

100 grams = 8.5735 tola. Formula: 100 ÷ 11.6638038 = 8.5735. A standard 10-tola gold bar weighs 116.638 grams.

5 tola = 58.319 grams. Formula: 5 × 11.6638038 = 58.319019 grams.

10 tola = 116.638038 grams. This is the weight of the standard 10-tola gold bar — one of the most commonly traded gold products in South Asia and the Gulf.

1 troy ounce = 2.6666... tola (precisely 31.1034768 ÷ 11.6638038 = 2.6667). Conversely, 1 tola = exactly 0.375 troy ounces (3/8 of a troy ounce).

1 tola = 11,663.8038 milligrams (since 1g = 1000mg, multiply 11.6638038 × 1000).

1 tola = 12 masha. The masha is a sub-unit of the tola: 1 masha ≈ 0.972 grams. Going further down: 1 masha = 8 ratti, and 1 ratti ≈ 0.1215 grams.

Both are used for precious metals, but they differ in weight and regional usage: 1 tola = 11.6638g (South Asia, Gulf), while 1 troy ounce = 31.1035g (international markets, as defined by the BIPM). The troy ounce is the global standard; the tola is the South Asian traditional standard. They are related: 1 tola = 0.375 troy ounces exactly.

1 kilogram = 85.7347 tola. Formula: 1000 ÷ 11.6638038 = 85.7347. So a 1 kg gold bar contains approximately 85.73 tolas.

The tola is used in India, Pakistan, Nepal, Bangladesh (where it's called "vori"), and GCC countries including UAE, Saudi Arabia, Kuwait, Qatar, and Bahrain. It is primarily used for gold, silver, and jewelry measurement.

In Bangladesh, the traditional gold weight unit is called vori (also bhori), equivalent to approximately 11.664 grams — essentially the same as the standard tola. The Bangladesh Jewellers' Association (BAJUS) uses the vori for daily gold price announcements.

The official standard in both countries is 1 tola = 11.6638038 grams. However, some Pakistani bazaar traders use an informal "market tola" of approximately 12 grams. Always specify which definition is being used in financial transactions.

India officially adopted the metric system in 1956, but the tola remained in widespread use due to its deep cultural roots in gold gifting, bridal jewelry customs, and established market infrastructure. Decades of gold market pricing, accounting, and cultural practices built around the tola made transition impractical. Today, both grams and tola are commonly used, with tola dominant in traditional jewelry bazaars.

The tola originated in ancient Vedic India, originally defined as the weight of 100 ratti seeds (Abrus precatorius). The word comes from the Sanskrit "tol" meaning "to weigh." It was formally standardized in 1833 by British colonial authorities as exactly 180 troy grains (11.6638038g). Read the full History of Tola.

Jewelers calculate price per tola by multiplying the per-gram gold price by 11.6638038. If gold is $60/gram, then: $60 × 11.6638 = $699.83 per tola. Additional charges (making charges, GST/taxes, purity adjustments) are then added to this base metal value.

A 10-tola gold bar weighs exactly 116.638038 grams and is equivalent to 3.75 troy ounces. It is the most popular gold investment bar format in India, Pakistan, Nepal, Bangladesh, and GCC countries. These bars are recognized on the MCX (Indian commodities exchange) and produced by major refiners.

1. Weigh the piece in grams (using a digital scale). 2. Convert to tola: Tola = Grams ÷ 11.6638038. 3. Find today's gold price per tola for your region. 4. Adjust for purity: multiply by purity factor (22K = 0.9167, 18K = 0.75, 24K = 1.0). 5. Result = gold value (excluding making charges). Use our Gold Price Calculator for step 3.

The most precise internationally standardized value is 11.6638038 grams (180 troy grains exactly). The rounded figure 11.664 is a common approximation with a difference of only 0.00018g per tola — negligible for most practical purposes but important for high-volume bullion trade.

It depends on the coin: A Sovereign (British gold coin) = 7.32g = 0.627 tola. A 1 troy ounce American Eagle = 31.1g = 2.667 tola. An Indian 10g gold coin (MMTC) = 10g = 0.8573 tola. A classic Indian tola coin = exactly 1 tola = 11.6638g.
