Value = grams × purity (karat / 24) × price per gram of pure gold. 1 troy ounce = 31.1035 g, 1 tola = 11.6638 g, 1 baht = 15.244 g, 1 luong = 37.5 g. Shops add making charges and buy back below the selling price.
The calculator above values gold from its weight, unit (gram, troy ounce, tola, baht, luong and others) and purity at a price you type in. This site does not show a live gold price unless a licensed or official source has been confirmed. Enter the rate you were quoted, or use the configured feed where one is shown.
Why gold has several units
Gold is priced in different units in different places:
- Troy ounce (oz t) is the unit for international gold prices, including spot quotes and futures. Spot quotes such as XAUUSD show US dollars per troy ounce.
- Gram is the metric unit. Many banks, refiners and digital gold apps use it.
- Tola is the traditional South Asian unit. Jewellers and bullion dealers in Pakistan usually quote gold per tola.
- Baht and luong are local gold units used in Thailand and Vietnam. They appear in the calculator for readers comparing those markets.

Troy ounce to gram
A troy ounce is not the ordinary ounce used for food and parcels, which is the avoirdupois ounce. The troy ounce is slightly heavier. If you confuse the two, every price you convert will be too low.
The calculator holds the exact number of grams per troy ounce. To find a price per gram yourself, divide the price per troy ounce by the grams in a troy ounce.
Tola to gram and gold tola weight
The tola was standardised in British India from the weight of the silver rupee coin, and Pakistan still uses that standard for gold. Jewellers divide a tola into smaller units called masha and ratti, which you may see on older receipts.
Before you compare prices, ask the dealer which gram figure they use for a tola. Some dealers round it, and on a large purchase a small difference in the conversion becomes a real amount of money. The calculator applies the standard tola weight.
Ounce to tola: converting a world quote into a local price
To turn an international quote into a rupee price per tola:
- Take the price in US dollars per troy ounce.
- Convert it to a price per gram: divide by the grams in a troy ounce.
- Convert it to a price per tola: multiply by the grams in a tola.
- Convert the currency: multiply by the USD/PKR rate. The SBP exchange rates page explains which official rates exist.
- Adjust for purity. World quotes are for fine gold. A jewellery price for lower-karat gold should be lower in proportion to its gold content. See Gold Karats and Purity.
The calculator does all of these steps. You only enter the price, the unit, the weight and the purity.
Why your result will not match the market exactly
A converted figure is a reference point, not the price you will pay. The local market price can differ for several reasons:
- dealer premiums or discounts
- making charges on jewellery
- import costs and taxes
- the exchange rate the dealer actually uses
- the gap between buying and selling prices
How Gold Price Is Set and Gold in Pakistan explain these differences. For costs by product, see Bars, Coins, Jewellery.
Spot quotes in troy ounces are also used for gold CFDs, which are contracts that track the price without delivering any metal. These products are leveraged and can lose money fast. Read Physical vs Paper Gold and Risk management before using them.
Frequent questions
How many grams are in a troy ounce?
A troy ounce is slightly heavier than an ordinary ounce. The calculator on this page applies the exact gram figure, so enter your weight there for a precise result.
What is the gold tola weight in grams?
Pakistan uses the standard tola inherited from British India. Ask your dealer which gram figure they use, because some round it. The calculator uses the standard value.
Is an ounce in a gold quote the same as a kitchen ounce?
No. Gold quotes use the troy ounce, which is heavier than the avoirdupois ounce used for everyday goods.
Why is the jeweller's price per tola higher than my conversion?
Your conversion leaves out making charges, dealer margins, taxes and import costs. It also may not use the same purity or exchange rate as the jeweller.
Does this page show a live gold price?
No. It shows a live price only when a licensed or official source has been confirmed. Otherwise, type in the price you were quoted.
