Quick Answer: Grams to Ounces
One gram is approximately 0.03527 ounces (1 g ≈ 0.03527 oz).
Conversely, 1 oz ≈ 28.35 g.
Formula: oz = g ÷ 28.349523125
Worked examples
- 1 g ≈ 0.03527 oz
- 10 g ≈ 0.3527 oz
- 25 g ≈ 0.8818 oz
Method and limitations
Divide grams by 28.349523125 (equivalently, multiply by about 0.035274). The result is in avoirdupois ounces, a unit of mass. Calculations use full-precision constants; answers in this box are rounded for readability (≈ marks a rounded value) and the calculator shows up to 9 significant figures. oz here is the avoirdupois ounce, a unit of mass: exactly 28.349523125 g, or 1/16 lb. It is not the troy ounce used for precious metals (31.1034768 g), and not the fluid ounce, which measures volume.
Each factor is exact by definition, derived from exact definitions, or a documented conventional value — see the methodology and sources.
