Gold Price per Tola Calculator: Tola to Grams and Dollars by Karat

Where 11.6638 Grams Comes From

The tola is old, but its weight is not a matter of opinion. British India's Standards of Weight Act, 1939 put it in a single line: "The standard tola, being a weight of 180 standard grains." The same section defines the seer as 80 tolas and lists the smaller units, which we get to further down.

The grain is the hinge. It is the same grain that sits underneath the troy system used for gold in the United States and London. The NIST Office of Weights and Measures conversion sheet gives one troy ounce as 480 grains and 31.1034768 grams, which makes one grain 64.79891 milligrams. Multiply by 180:

180 × 0.06479891 g = 11.6638038 g

And because a troy ounce is 480 grains, a tola is 180 ÷ 480 = 0.375 troy ounce. Eight tolas make exactly three troy ounces. That tidy ratio is the reason a tola price and an international ounce price translate so cleanly: a tola of pure gold is always three-eighths of the ounce price.

India moved to metric weights after 1956, and the 1939 Act was repealed along the way, so the tola is no longer a legal trading unit there. It never stopped being a household one. You will also see it written as 11.664 g (rounded to three decimals) or 11.66 g. Both are fine for a single bangle. They start to matter on larger weights, as the 120-tola example below shows.

Tola, Gram and Troy Ounce Conversion Table

Every row is the count of tolas × 11.6638038 g. Troy ounces are tolas × 0.375; pennyweight (the unit US jewelers weigh in) is tolas × 7.5.

Going the other way: grams ÷ 11.6638 = tolas, so a kilogram is 85.74 tolas. If you need grains, baht or tael as well, the gold weight calculator handles every unit in one place.

What One Tola Is Worth at Each Karat

Assume gold at $4,400 per troy ounce, which works out to $141.46 per gram of pure gold. Per-tola melt value is then 11.6638 g × purity × $141.46.

A sanity check needs no calculator at all: spot price × 0.375 × purity. For 22K, $4,400 × 0.375 × 0.9167 = $1,512.55, within three cents of the table (the gap is rounding in the per-gram price). These are melt values, the floor of what the metal is worth, not what a buyer hands over.

If your piece is 22K, the 22K gold calculator goes further on that karat alone, including how per-gram and per-tola figures move with the market.

A 10-Gram Rate Is Not a Tola Rate

Here is the most expensive mix-up on this page. Plenty of gold rates are published per 10 grams, not per tola. India's bullion benchmark is one example: the India Bullion and Jewellers Association rate page labels its figures "Gold rates per 10gm" and notes they exclude 3% GST and making charges (read October 2026). A 10-gram figure looks like a tola figure, sits in the same place on a rate board, and is 14.3% smaller, because a tola is 1.16638 times ten grams.

The fix is one multiplication:

• Per-10 g rate → per-tola rate: × 1.16638
• Per-tola rate → per-10 g rate: ÷ 1.16638
• Either one → per gram: divide by 10, or by 11.6638

So a board showing $1,300 per 10 g of 22K is quoting $1,516.29 per tola, and a $1,516.29 tola quote is $130.00 per gram. Same price, three costumes. If you read the 10-gram figure as a tola price, you would think the gold was about $216 a tola cheaper than it is, and you would accept an offer that is short by the same margin.

We are not going to tell you which unit a particular city's jewelers use today; that changes by market and by shop, and we have not surveyed them. What you can do is ask one question before you compare anything: "Is that per tola, per 10 grams, or per gram?" If the answer is vague, the quote is not ready to compare.

Converting a Local Quote Into Something Comparable

Suppose you are selling 22K jewelry and two buyers give you prices in different units. Buyer A offers $1,290 per tola. Buyer B offers $1,120 per 10 grams. B's number is smaller. B's offer is better.

That conversion is all a gold price per tola calculator does under the hood, and it takes three steps by hand:

1. Convert both to dollars per gram. A: $1,290 ÷ 11.6638 = $110.60/g. B: $1,120 ÷ 10 = $112.00/g.
2. Work out 22K melt per gram at the same moment. At our assumed price, $141.46 × 0.9167 = $129.68.
3. Divide offer by melt. A pays 85.3% of melt; B pays 86.4%.

On a 50-gram set that gap is (112.00 − 110.60) × 50 = $70, which is real money for one question about units. Both offers sit inside the 70–90% band that online refiners and the better coin dealers typically pay, so neither buyer is out of line; one is simply better, and the unit hid it. The gold price per gram calculator shows live per-gram melt for every karat, which is the number you should divide by.

The same method works for buying, where the figure you compare is the price above melt (making charges and premium) rather than the share below it.

Three Tolas of 22K, Start to Finish

"I have 3 tolas of gold, how many grams is it?" is one of the questions that brought this page into existence, so let's answer it completely and then keep going to dollars.

You could skip straight to a gold price per tola calculator, but doing it once by hand shows exactly where the money is.

Grams. 3 × 11.6638 = 34.99 g. If the family figure is "three tola," put the jewelry on a scale anyway; remembered weights are often rounded, and any stones, lac fill or non-gold clasps add weight that is not gold.

Pure gold. At 22K: 34.99 × 0.9167 = 32.08 g of fine gold.

Melt value. 32.08 × $141.46 = $4,538 at an assumed $4,400 per troy ounce.

What buyers would pay, using the usual share-of-melt bands:

The spread between the best and worst outlets on the same 35 grams is more than $3,000. Every selling guide on this site boils down to the same lesson: know your weight and karat, and get more than one quote.

The 120-Tola Question

Another real search: "gold weight calculator, tulas to grams, total 120 tulas." The conversion is quick: 120 × 11.6638038 = 1,399.66 g, just under 1.4 kilograms, or exactly 45 troy ounces.

If that is 22K jewelry, the fine gold is 1,399.66 × 0.9167 = 1,283.07 g, worth about $181,502 in melt at $4,400 per ounce. If it is 24K bar or coin, it is about $197,797.

At this size, rounding stops being harmless. Using 11.66 g instead of 11.6638 g drops 0.46 g across 120 tolas, about $59 of 22K gold, which is tolerable. Treating a tola as 10 grams drops 199.66 g, roughly $25,891 of 22K melt, which is not. A lot this large also deserves a written assay and offers from more than one refiner rather than a counter quote, and a gold calculator estimate is the starting point for that conversation, not the end of it.

Masha and Rati: The Smaller Pieces

Old receipts and family notebooks sometimes go below the tola. The 1939 Act's own table of sub-multiples sets them out:

• 1 masha = 1/12 tola = 0.972 g
• 1 rati = 1/96 tola (one-eighth of a masha) = 0.1215 g
• ½ tola = 6 masha; ¼ tola = 3 masha

So "2 tola 4 masha" is 2 × 11.6638 + 4 × 0.972 = 27.22 g. Convert each part to grams, add, and only then apply purity. The 916 gold price calculator page also covers the South Indian sovereign, which is a separate 8-gram unit and easy to confuse with the British coin of the same name.

A Note on Zakat

The tola-based gold nisab is 7.5 tola, which is 87.48 g; other scholars use 85 g, and schools differ on whether worn jewelry counts. The zakat on gold calculator lays out both conventions; treat it as arithmetic, not a religious ruling, and confirm your obligation with a scholar you trust.
