Tip: A US cup always holds the same volume — grams change because density changes.

Why cups don't convert to a fixed weight
A US cup is always the same volume — 236.588 ml — but the same cup filled with flour, sugar, or butter will weigh a different amount because each ingredient packs into that volume differently. That's why this converter asks for an ingredient first: the grams-per-cup value behind the scenes is what makes the result accurate instead of a rough guess.
