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 40g of it fills more of a cup than 40g of honey, which is thick and heavy. Density — not volume — decides the weight.
All-Purpose Flour
40g ≈ ⅓ cup
Butter
40g ≈ ⅛ cup
