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.
