The Simple Answer
1 ounce (oz) = 28.3495 grams (g). If you only need a quick conversion for everyday use (like cooking or portioning), remember:
1 oz ≈ 28 grams

Why the Difference Exists
The ounce is a unit from the imperial system (used mostly in the U.S.), while the gram is metric (used worldwide). When converting between them, exact decimals can vary depending on rounding or if referring to:
- Ounce (Avoirdupois) – Regular ounce used for weight; equals 28.3495 g.
- Troy ounce – Used for precious metals; equals 31.1035 g.
That’s why jewelers, for instance, use a slightly different number.
Everyday Use Examples

- Science labs: Exact conversions matter—use 28.3495 g per oz for precision.
