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 30g of it fills more of a cup than 30g of honey, which is thick and heavy. Density — not volume — decides the weight.

All-Purpose Flour

30g ≈ ¼ cup

Butter

30g ≈ ⅛ cup
