How it works

An avoirdupois ounce is 1/16 of a pound, exactly 28.349523125 g, so ounces = grams ÷ 28.349523125 (× 0.035274). 100 g is 3.53 oz, 250 g (a common butter block outside the US) is 8.82 oz and 1 kg is 35.27 oz.

This is the ounce for food, parcels and letters. It is not the fluid ounce (a volume, 29.57 mL in the US) and not the troy ounce used for gold and silver (31.10 g). If your recipe gives cups rather than grams, use the cups-to-grams converter, which accounts for the ingredient.

How to convert grams to ounces

Formula: oz = g × 0.0352739619496.

Divide the grams by 28.349523125, the exact number of grams in an avoirdupois ounce. Worked example for a 250 g block of butter: 250 ÷ 28.349523125 = 8.818 oz.

Above 16 oz, split the result into pounds and ounces: 500 g = 17.64 oz = 1 lb 1.6 oz. This is the weight ounce for food and parcels, not the fluid ounce used for liquids.
