Grams to Ounces (Food) Converter
Convert grams to ounces and pounds for food weights, using the exact 28.3495 grams-per-ounce ratio bakers and cooks rely on.
How it works
Ounces = grams ÷ 28.349523 · Pounds = grams ÷ 453.59237
One avoirdupois ounce — the ounce used for food weight — is exactly 28.349523 grams, and a pound is 16 of those ounces (453.59 g). This is a weight conversion, so it is independent of the ingredient: 100 g of flour and 100 g of water both convert to the same 3.53 oz. Do not confuse the weight ounce with the fluid ounce (a volume of about 29.57 ml); a kitchen scale measures the weight ounce.
Worked example
A recipe calls for 250 g of butter and your scale reads in ounces. Dividing by 28.3495 gives 250 ÷ 28.3495 = 8.82 oz, which is 250 ÷ 453.59 = 0.551 lb, or 0 lb 8.8 oz.
Frequently asked questions
How many grams are in an ounce of food?
Exactly 28.349523 grams, usually rounded to 28.35 g in recipes. So 4 oz is about 113 g, 8 oz (half a pound) is about 227 g, and 16 oz (a pound) is 453.6 g.
Is this the same ounce used for liquids?
No. This converts the avoirdupois (weight) ounce measured on a scale. A fluid ounce is a volume of about 29.57 ml, and 1 fl oz of a liquid only weighs 1 oz for pure water — denser or lighter ingredients differ.
Why do bakers prefer grams over ounces?
Grams are a finer, whole-number unit, so weighing in grams avoids awkward fractions of an ounce and reduces rounding error. This matters most in baking, where small ratio changes affect texture and rise.
