Measurement notes
- Butter is often sold in sticks in the US, and one stick equals 113g (about half a cup).
- Soft butter should be packed firmly into the measuring cup to avoid air pockets that skew the weight.
- Cold butter is harder to measure accurately by volume — let it soften to room temperature first.

Measuring step this site recommends: packed into cup.
When sources disagree, follow your recipe: use its gram weights if it gives them, or measure the way its author did. The adopted value is one stated convention, not a correction of the other sources.
A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
