  • These figures use the metric cup (250 ml). A US cup is slightly smaller at 240 ml, so it holds a little less. Use the US cup converter →
  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →

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.
