  • 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 →

Kidney beans are large, dark-red beans common in chilli, soups, and salads. One metric cup (250 ml) of cooked, drained kidney beans weighs around 185 grams or 6.53 ounces. When a recipe lists beans in cups but you are working from a can or a pot, converting by weight keeps the bean ratio right.

A 400 g can drains to roughly 240 g of beans, a little over one metric cup, while recipes switch between cups, grams, and cans. Weighing in grams ties them together so a chilli or salad lands on target.
