Britain has large South Asian communities, so the tola is a familiar word for gold jewellery, coins and bars. UK shops, though, work in metric units. This page explains how the two fit together in the UK and how to read tola and grams side by side. For the full background of the unit, see our central precious metals mass calculator.
How the Tola Is Used in the UK
In the UK the tola is a way of talking about gold, not a unit of trade. Families who know gold in tola may hear the word from a jeweller or relative, while the label, receipt and shop scale show grams. Tola-sized coins and bars are sold in the UK, and the weight that counts is the gram figure shown on the item or in the listing.
UK Measurement Rules: Metric First
UK law decides which units can be used when something is sold:
This is why UK listings and receipts usually show gold in grams, and sometimes in troy ounces for bullion.
| Unit | Grams | Used for gold in UK trade? |
|---|---|---|
| Gram | 1 g | Yes |
| Kilogram | 1,000 g | Yes |
| Troy ounce | 31.1035 g | Yes, for precious metals |
| Metric carat | 0.2 g | No, only for gemstones and pearls |
| Tola | 11.6638 g | Not a unit listed in UK law |
Does the Tola Change in the UK?
No. A tola in the UK is the same standard tola of 180 troy grains. UK law defines the troy ounce as 31.1034768 g, and the tola is exactly 3/8 of that, which gives 11.6638 g. England, Scotland, Wales and Northern Ireland all use the same weight. The rules for selling goods come from separate laws for Great Britain and Northern Ireland, but the tola itself does not change.
How to Convert Tola to Grams in the UK
- 1Write down the weight in tola.
- 2Multiply by 11.6638.
- 3Round to two decimal places.
Examples:
Using the conventional factor, 3.4294 tola × 11.6638 ≈ 40 g. Enter a tola amount in the calculator above to get its gram weight.
Reading Tola and Grams Together in the UK
Where to Buy Gold in the UK
Whether you are comparing a family tola description with a UK gram-based receipt or considering jewellery and bullion, keep the unit conversion separate from legal, tax and investment questions.
Hallmarking and tax treatment depend on the item and the applicable rules. Some gold articles are exempt from compulsory hallmarking, and only gold meeting HMRC's complete definition of investment gold receives the relevant VAT treatment. Check the current official guidance for the specific item.
| LOCATION / HUB | FAMOUS STREETS & DISTRICTS | SPECIALTY |
|---|---|---|
| London (Hatton Garden) | Hatton Garden, Greville Street (EC1) | Historic UK jewellery and diamond center, certified bullion dealers, institutional bars (Metalor, PAMP), bespoke goldsmiths |
| London (South Asian Hubs) | The Broadway (Southall), Green Street (Upton Park), Tooting High Street | Britain's largest 22K Asian gold hubs, bridal sets, tola-measured jewellery, traditional bangles, mangalsutras, gold coins |
| Birmingham (Jewellery Quarter) | Hockley, Vyse Street, Warstone Lane | Produces over 40% of UK jewellery, home to the Birmingham Assay Office, direct trade workshops, competitive manufacturing rates |
| Leicester (The Golden Mile) | Belgrave Road, Melton Road | Famous South Asian retail strip, 22K Indian wedding jewellery, festival gold purchasing (Diwali, Eid), custom bullion trade |
| Manchester & Bradford | Wilmslow Road (Curry Mile, Manchester), Leeds Road (Bradford) | Northern England hubs for 21K and 22K Pakistani and Indian bridal ornaments, festive jewellery, coin trade, resizing & repairs |
| National Bullion & Mint | The Royal Mint, LBMA-Accredited UK Bullion Dealers | Gold coins and bars; check the item-specific hallmarking, tax and investment-gold criteria before purchase |
1. Check the Hallmark: Check whether the item requires a hallmark and whether an exemption applies; UK rules include weight and other exemptions.
2. Weight in Grams: While the jeweller may discuss pieces in tola, ensure the official receipt and scales explicitly state the net weight in grams.
3. Investment Gold VAT: Do not assume that all 24K items or coins are VAT-exempt. HMRC's definition includes purity, form, weight and—for coins—additional conditions. Confirm the current treatment before purchase.
