Cup & Gram

Ounces to Grams

One ounce equals 28.35 grams, so multiply ounces by 28.35: 4 oz is 113 g (a stick of butter), 8 oz is 227 g, and a pound (16 oz) is 454 g. These are weight ounces — fluid ounces measure volume and are a different unit.

Dry ounces vs fluid ounces

"8 oz of flour" means weight (227 g), but "8 fl oz of milk" means volume (1 cup, 237 ml). They only coincide for water-like liquids. When a US recipe says "ounces" for a dry ingredient, weigh it; when it says fluid ounces, use a liquid measuring cup — or convert through grams to cups for the ingredient.
