How It Works

Ounces = Grams × 0.035274. The conversion factor 0.035274 is derived from the exact definition of the avoirdupois ounce: 1 ounce = 28.349523125 grams exactly, so 1 gram = 1/28.349523125 oz ≈ 0.035274 oz. The calculator uses this rounded constant, which introduces an error of less than 0.0001% — negligible for cooking, nutrition, or shipping. The result distinguishes dry ounces (avoirdupois weight) from fluid ounces, which measure volume and are not the same. A fluid ounce of water weighs approximately 29.57 grams, while an avoirdupois ounce weighs 28.35 grams — close but not identical. This calculator performs the weight (avoirdupois) conversion only.
