One troy ounce of gold equals 31.1035 grams — not the 28.35-gram kitchen ounce you'd use to weigh flour. That 2.75-gram gap matters more than you'd think: if you misuse the wrong ounce, you'll misread a bullion price by nearly 10%. At the time of writing, the gold spot price is $4,126.43 per troy ounce, which works out to $132.67 per gram of pure 24K gold — and every price you see on a gold exchange, futures contract, or bullion dealer's website is always in troy ounces.
The Troy Ounce vs. The Kitchen Ounce — Why It Matters to You
The troy ounce is a unit that goes back centuries to the Champagne fairs of medieval France, and the global precious-metals market never switched away from it. Today, when the London Bullion Market Association fixes a gold price, when COMEX trades a futures contract, or when a bullion dealer in Dubai quotes a bar price — they all mean 31.1035 grams.
The avoirdupois ounce (the one on your kitchen scale) is 28.3495 grams. That's used for groceries, postal weights, and everyday goods. Gold is never quoted in avoirdupois ounces.
Here's the practical consequence: if you're comparing an online spot price to a local jeweler's per-gram price, you must divide the spot price by 31.1035, not by 28.35. Dividing by the wrong number gives you a per-gram figure that's about 9.7% too high — enough to make a fair deal look like a rip-off, or a bad deal look reasonable.
Quick reference:
| Unit | Grams | Notes |
|---|
| 1 troy ounce | 31.1035 g | Used for all bullion and spot pricing |
| 1 avoirdupois ounce | 28.3495 g | Everyday/kitchen ounce — not used for gold |
| 1 kilogram | 1,000 g | = 32.1507 troy ounces |
| 1 tola (South Asia/Gulf) | 11.6638 g | = 0.375 troy ounces |

For 22K and 21K — the karats most commonly sold as jewelry across the GCC and Egypt — the per-gram prices at time of writing are:
| Karat | USD/g | EGP/g | SAR/g | AED/g | KWD/g | QAR/g |
|---|
| 24K | $132.67 | 6,514.73 | 497.50 | 487.22 | 41.10 | 482.91 |
| 22K | $121.62 | 5,972.05 | 456.06 | 446.64 | 37.68 | 442.68 |
| 21K | $116.08 | 5,700.39 | 435.32 | 426.32 | 35.96 | 422.55 |
| 18K | $99.50 | 4,886.05 | 373.13 | 365.42 | 30.82 | 362.18 |
If you're buying 22K jewelry in Dubai right now, you're paying roughly AED 446.64 per gram before making charges. A 10-gram bracelet costs around AED 4,466 in gold content alone — the jeweler's workmanship fee comes on top.
Why Bullion Is Quoted Per Ounce but Jewelry Is Sold Per Gram
This confuses a lot of buyers, and the answer is purely historical and practical. The international bullion market — London, New York, Zurich — standardized on the troy ounce because large bars (400 oz London Good Delivery bars) and coins were the tradable units. Changing that convention now would create chaos across decades of contracts and pricing databases.
Local jewelry markets in Cairo, Riyadh, Dubai, and Kuwait City work in grams because that's the unit that makes sense for small retail transactions. A ring weighs 3–5 grams; a chain weighs 8–15 grams. Quoting those in fractions of a troy ounce would be needlessly confusing for everyday shoppers.
So you end up with a split: spot price in troy ounces for the global wholesale market, gram pricing for retail jewelry. The math bridge between them is always: spot price ÷ 31.1035 = price per gram of 24K. Then multiply by the karat fraction (22/24, 21/24, 18/24) to get the alloy price.
The smart move: if you're buying gold for investment or resale, 21K or 22K bullion coins and small bars give you the best balance of liquidity and lower making charges compared to 18K jewelry. The catch is that 18K pieces often carry heavier design work, so part of the premium is genuinely craftsmanship — it's not pure overcharging.
What Our Price Records Show About Volatility — and Why the Gram Price Swings Hard
Since DahabPulse began recording daily closing prices (~8 weeks ago), gold has been anything but stable. Our recorded high was $4,751.72 per troy ounce on May 11, 2026 — that translates to roughly $152.75 per gram of 24K, or about EGP 7,502 per gram at current exchange rates. Our recorded low was $3,996.16 on June 24, 2026, equal to roughly $128.47 per gram.
That's a swing of over $755 per troy ounce — or nearly $24 per gram — within eight weeks. Our latest recorded close was $4,044.65 on July 1, 2026, with gold up about 1.2% over the past 7 days but down 9.8% over the past 30 days. The spot price at time of writing ($4,126.43) sits above that July 1 close, suggesting some recovery momentum heading into the weekend.
For Egyptian buyers especially, the gram price in EGP is doubly sensitive: it moves with both the gold spot price and the USD/EGP rate. At EGP 6,514.73 per gram of 24K right now, anyone who bought near our recorded high in May was paying the equivalent of roughly EGP 7,500 per gram. That's a painful ~13% drop in gram value over eight weeks — which is exactly why watching the per-gram price, not just the headline ounce figure, is what actually protects your purchase.

Frequently Asked Questions
Q: How many grams are in one ounce of gold?
One troy ounce of gold equals exactly 31.1035 grams. This is the standard used by every gold exchange, bullion dealer, and futures market worldwide. Do not confuse it with the avoirdupois ounce (28.3495 grams), which is used for everyday goods but never for precious metals.
Q: How do I convert an ounce gold price to a price per gram?
Divide the troy ounce price by 31.1035 to get the price per gram of pure 24K gold. For example, at a spot price of $4,126.43 per troy ounce: $4,126.43 ÷ 31.1035 = $132.67 per gram. For lower karats, multiply that result by the karat fraction — for 21K, multiply by (21 ÷ 24 = 0.875) to get $116.08 per gram.
Q: What is one troy ounce of gold worth in Egyptian pounds right now?
At the time of writing, one troy ounce of pure 24K gold is worth approximately EGP 202,644 (based on $4,126.43 spot × EGP 49.11 per USD). Prices move daily — check the Egypt gold price page for the live figure. Over the past 8 weeks, our recorded gram price in EGP has ranged from the equivalent of roughly EGP 6,304 (near the June 24 low) to roughly EGP 7,502 (near the May 11 high).
Q: Why do jewelers in the Gulf sell gold by the gram, not by the ounce?
Local jewelry retail uses grams because rings, chains, and bangles weigh just a few grams — quoting them in fractions of a troy ounce would be impractical. The international wholesale and investment market uses troy ounces because that's the historical standard for large bullion bars and coins. Both are measuring the same metal; the unit just depends on context.
Q: Is a half-ounce gold coin really 15.55 grams?
Yes. A half troy ounce equals 15.5518 grams (31.1035 ÷ 2). Bullion coins like the half-ounce South African Krugerrand, British Britannia, or Canadian Gold Maple Leaf are all struck to this weight in 24K or 22K gold. At time of writing, the gold content of a half-ounce coin is worth approximately $2,063 — use the DahabPulse gold calculator to convert that into dirhams, riyals, or pounds instantly.
The troy ounce is the language of the global gold market; the gram is the language of your local jeweler. Knowing both — and knowing exactly how to convert between them — means you'll never pay more than you should, and you'll spot a bad deal before you've handed over your cash.
