💡 Did You Know?
Gold is not weighed in the same ounce as your groceries. The troy ounce used for precious metals is heavier than the standard ounce, which is why converting with the wrong figure produces a price that looks suspiciously off.
📊 DATA & STATS
One troy ounce is 31.1035 grams. One standard ounce is 28.3495 grams. The difference is about 10%, which is more than enough to make a converted gold price look wrong if you use the wrong one.
The short answer is 31.1035 grams. The longer answer explains why there are two different ounces, which one gold uses, and how to convert a global gold price into the ringgit-per-gram figure you will actually see in a Malaysian shop.
Troy Ounce vs Standard Ounce
Precious metals are traded in troy ounces, a unit that predates the modern metric system and survives specifically in gold, silver, platinum and palladium markets. Everything else you weigh day to day uses the avoirdupois ounce.
- 1 troy ounce = 31.1035 grams
- 1 standard ounce = 28.3495 grams
- 1 kilogram = roughly 32.15 troy ounces
When you see a gold price quoted per ounce anywhere in the world, it is the troy ounce.
Why This Matters in Malaysia
Malaysian shops quote ringgit per gram. The global market quotes US dollars per troy ounce. To compare them you need both the exchange rate and the correct gram conversion. Using 28.35 instead of 31.10 inflates the per-gram figure by around 10%, which is enough to make a fair price look expensive or an expensive one look fair.
Converting a Global Price to Ringgit per Gram
The sequence is simple enough to do on a phone:
- Start with the US dollar price per troy ounce.
- Multiply by the current MYR/USD rate to get ringgit per troy ounce.
- Divide by 31.1035 to get ringgit per gram.
The result is the raw metal value. A shop quote will sit above it, and that gap is the premium covering fabrication, certification and margin. Comparing that premium across sellers is more useful than comparing headline prices.
Other Units You May Meet
Some traditional Malaysian and regional contexts still use mayam, a jewellery weight roughly equal to 3.75 grams. If a piece is quoted in mayam, convert to grams before comparing it against anything else, otherwise you are comparing different units without noticing.
