When a recipe calls for a cup of chopped onion and you would rather not guess, the gram weight keeps your prep on track. One metric cup (250 ml) of chopped onion weighs 160 g (5.64 oz). This converter moves between cups, grams, tablespoons, and more.

Chopped onion packs loosely or tightly depending on how fine you cut it, so the cup weight drifts. Measuring in grams keeps a soffritto, soup base, or curry consistent every time.
