Learn about gold weight units, including grams, pavan and tola in Sri Lanka. Understand gold weight conversions to compare prices when buying or selling gold jewellery.

Gold Weight Units Explained: Grams, Pavan and Tola

Gold is measured in different units around the world, including grams, pavan, tola and troy ounces. These units are commonly used when buying gold jewellery, selling pre-owned gold or checking international gold prices.

In Sri Lanka, gold prices are often discussed in grams and pavans, while international gold prices are commonly quoted per troy ounce. Understanding these measurements helps you compare prices, check quotations and make informed decisions when buying or selling gold.

Whether you are purchasing a new gold necklace, investing in gold or planning to sell jewellery you already own, knowing how gold weight is measured can help you understand its value more clearly.

Why Gold Weight Matters When Buying or Selling Gold

Gold weight is one of the key factors used to calculate the value of gold. However, weight alone does not determine the final price. Gold purity, the applicable market rate and the transaction’s pricing terms also play important roles.

When buying gold jewellery, understanding the weight helps you compare similar items and assess the price you are paying. When selling gold, knowing the weight allows you to check the buyer’s calculations and compare offers more confidently.

For example, two gold necklaces may weigh exactly 10 grams but have different values because one is 22K gold and the other is 18K gold. The difference comes from their gold content.

Understanding both weight and purity is therefore essential for anyone participating in the gold market.

The Main Gold Weight Units

Gold is traded using several weight units, depending on the country, market and type of transaction.

Weight Unit	Approximate Weight	Common Use
Gram	1 gram	Gold jewellery and retail transactions
Pavan (Sovereign)	8 grams	Commonly used in Sri Lanka and South India
Tola	11.66 grams	Traditional South Asian gold trading
Troy Ounce	31.1035 grams	International gold prices and bullion
Kilogram	1,000 grams	Large quantities of gold and bullion

Important: A pavan is generally treated as 8 grams in Sri Lanka. Always confirm the weight unit used in a quotation before comparing prices.

Gram: The Standard Unit for Gold Jewellery

The gram is one of the most widely used units for measuring gold jewellery. Gold necklaces, rings, bracelets, earrings and other items are commonly weighed in grams during purchases and valuations.

When buying jewellery, the weight helps you understand how much gold the item contains by mass. However, the total retail price may also include making charges, design costs, applicable taxes and other fees.

When selling jewellery, the weight is used alongside the gold’s purity to determine its estimated gold value. The amount offered by a buyer may differ from the original retail price because jewellery-making charges and retail markups are not necessarily recovered when selling.

When comparing gold prices, always check the weight, purity and applicable rate rather than relying on weight alone.

Pavan: A Common Gold Weight Unit in Sri Lanka

The pavan, also known as a sovereign, is a traditional gold weight unit commonly used in Sri Lanka and South India.

One pavan is generally equivalent to 8 grams. Gold jewellery prices may be quoted per pavan, particularly in everyday conversations between buyers and sellers.

Understanding the conversion is useful when comparing a per-pavan quotation with a per-gram rate.

How to Convert Pavan into Grams

Use this simple formula:

Weight in grams = Number of pavans × 8

For example:

1 pavan = 8 grams
2 pavans = 16 grams
3 pavans = 24 grams
5 pavans = 40 grams

How to Convert a Pavan Price into a Gram Price

Suppose a seller quotes a price of LKR 240,000 per pavan for a particular gold product.

To calculate the equivalent price per gram:

LKR 240,000 ÷ 8 = LKR 30,000 per gram.

This is a mathematical conversion of the quoted rate, not a confirmation that the price is appropriate for every gold item. Before buying or selling, confirm the applicable rate for the specific karat and transaction.

Tola: A Traditional South Asian Gold Weight Unit

The tola is another traditional unit used in parts of South Asia, particularly in gold trading.

One tola is approximately 11.66 grams, making it heavier than one pavan.

Because these units represent different weights, a price quoted per tola cannot be compared directly with a price per pavan without conversion.

Pavan vs Tola

Consider the following comparison:

1 pavan = 8 grams
1 tola ≈ 11.66 grams
1 tola is approximately 1.46 times the weight of a pavan.

If you are buying gold from a market where prices are quoted per tola, convert the quotation into a per-gram rate before comparing it with Sri Lankan prices. The same principle applies when selling gold. Comparing equivalent weights makes it easier to evaluate offers fairly and avoid misunderstandings.

Troy Ounce: How International Gold Prices Are Measured

International gold prices are commonly quoted in US dollars per troy ounce.

One troy ounce is approximately 31.1035 grams. It differs from the ordinary ounce used for everyday goods, which weighs approximately 28.35 grams.

The troy ounce is particularly important because international gold prices influence gold rates in local markets, including Sri Lanka.

Several factors can affect the local price, including:

International gold market movements.
The exchange rate between the US dollar and the Sri Lankan rupee.
Local supply and demand.
Market conditions and the pricing policies of individual businesses.

When checking international gold prices, remember that a quoted price per troy ounce is not the same as the price you will pay for jewellery in a shop or receive when selling pre-owned gold.

Retail jewellery prices may include making charges and other costs. Gold-buying offers may instead be based on the item’s verified purity, weight and the buyer’s applicable buying rate.

Kilogram: A Unit for Larger Quantities of Gold

A kilogram equals 1,000 grams and is commonly used to measure larger quantities of gold, including bullion.

Although most jewellery buyers and sellers deal with grams or pavans, kilograms are relevant in large-scale gold trading, bullion transactions and discussions about gold reserves.

For example:

1 kilogram = 1,000 grams.
1 kilogram = 125 pavans, using the 8-gram conversion.
1 kilogram is approximately 85.74 tolas.

Understanding these conversions can be useful when comparing information from different gold markets or reviewing investment-related gold prices.

How to Calculate Gold Weight and Purity

Weight and purity work together to determine the amount of pure gold contained in an item.

Gold purity is commonly expressed in karats. Pure gold is represented by 24K, while 22K and 18K gold contain smaller proportions of pure gold.

Pure gold content = Total weight × (Karat ÷ 24)

For example:

24K gold contains approximately 100% gold.
22K gold contains approximately 91.67% gold.
18K gold contains approximately 75% gold.
14K gold contains approximately 58.33% gold.

These percentages assume the stated karat is accurate.

A Worked Example: Buying or Selling a 22K Gold Chain

Suppose a gold chain weighs 3 pavans and is confirmed to be 22K gold.

Step 1: Convert the weight into grams.

3 pavans × 8 grams = 24 grams.

Step 2: Calculate the approximate pure gold content.

24 grams × (22 ÷ 24) = 22 grams of pure gold.

The chain weighs 24 grams and contains approximately 22 grams of pure gold.

When buying this chain, its gold content helps you understand its material value alongside any making charges and other applicable costs.

When selling it, the buyer may use the verified weight, purity and applicable buying rate to calculate an offer. The final amount is not necessarily equal to 22 grams multiplied by the international gold price, as local pricing and valuation methods also matter.

How Gold Weight Affects the Price When Buying Gold

If you are planning to buy gold jewellery, understanding weight units can help you compare items and understand the price breakdown.

Here are a few points to consider:

Check the weight in grams. Confirm the stated weight of the jewellery before making a purchase.
Confirm the purity. A 22K item and an 18K item of the same weight contain different amounts of gold.
Understand the price per unit. Check whether the quoted gold rate is per gram, pavan or another unit.
Ask about additional charges. Making charges, design costs, taxes and other applicable fees may affect the final retail price.
Compare similar items. Consider weight, purity, workmanship and the total price rather than comparing the weight alone.

These steps can help you make a more informed purchasing decision and understand what contributes to the price you pay.

How Gold Weight Affects the Price When Selling Gold

Keep the following points in mind:

Confirm the weight. Ask to see the jewellery weighed on a digital scale.
Check the purity. Different items may contain different karat levels, even if they look similar.
Confirm the buying rate. Ask which rate applies to your item’s purity and whether the rate is quoted per gram or per pavan.
Compare equivalent quotations. Convert different rates into the same weight unit before comparing offers.
Understand the final valuation. Ask how the weight, purity and applicable buying rate contribute to the amount offered.

The original retail price of jewellery may include design and manufacturing costs that are not fully reflected in a resale offer. This is why understanding the item’s gold content and the buyer’s pricing method is important.

Common Mistakes to Avoid When Comparing Gold Prices

Even when the quoted prices appear straightforward, using different units can lead to inaccurate comparisons.

Watch out for these common mistakes:

Confusing pavan with tola: One pavan is approximately 8 grams, while one tola is approximately 11.66 grams.
Ignoring gold purity: Two items of the same weight may have different values if their karat levels differ.
Comparing retail and buying rates directly: The price charged when buying new jewellery may differ from the amount offered when selling used jewellery.
Forgetting additional costs: Retail jewellery prices may include making charges, taxes and other fees.
Assuming the international rate is the final local price: International gold prices are only one influence on local prices and do not automatically represent a retail or resale quotation.

The easiest way to avoid these mistakes is to confirm the weight, purity, unit and applicable rate before agreeing to a transaction.

Final Thoughts

Grams, pavans, tolas, troy ounces and kilograms are different units used to measure gold. Understanding their differences helps you compare prices accurately, whether you are buying jewellery, investing in gold or selling items you already own.

For a reliable comparison, convert the weight and quoted price into grams, confirm the gold’s purity, and ask how the final price is calculated. This makes it easier to understand the quotation and evaluate your options.
