Why the Cup Value Changes

Water weighs about 236g per cup, which is why some converters use it as a default. But flour is airy and light, so 3g of it fills more of a cup than 3g of honey, which is thick and heavy. Density — not volume — decides the weight.

All-Purpose Flour

3g ≈ ⅛ cup

Butter

3g ≈ 0 cup
