  • A tablespoon here is the 15 ml metric standard, about 16.67 to a metric cup, the same size as a UK tablespoon. A US tablespoon is smaller at 14.79 ml, so US cooks measuring with US spoons need slightly more. An Australian tablespoon is larger at 20 ml, so it holds about a third more.

  • A little over or under won't ruin the bake, though it can nudge the final taste or colour.

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.
