This is exactly the question a plain calculator cannot answer: it does not know which ingredient you mean. 3 cups of honey weighs 1020 g while the same volume of oats is only 270 g — nearly four times the difference, purely from density. When a recipe matters, weigh rather than scoop.

Frequently asked questions

How many grams is 3 cups?

It depends on the ingredient: about 360 g for flour, 600 g for sugar, or 681 g for butter.

Why does 3 cups weigh different amounts?

Because a cup measures volume, not weight. Denser ingredients like honey or sugar weigh far more per cup than light ones like oats or flour.

Is it better to measure by cups or grams?

Grams. Weighing removes the variation caused by how tightly an ingredient is packed, which is the main source of baking inconsistency.
