Every figure below is one measured number — 227 g per US cup — scaled. That is why this table and the converter above it cannot disagree.
One cup, side by side
Does melted butter weigh the same as solid butter?
227 g per cup, the same as solid butter — and taken from solid butter's definition rather than from a measured density. It is worth being exact about which question that answers. Measure a cup of butter solid and melt it, and you have 227 g; this page is right for that. A cup filled with already-melted butter is a different measurement, and dishscale has no sourced density for liquid butterfat, so it does not claim one — for scale, the oils on this site run 0.913 to 0.921 g/ml, which would put a poured cup somewhere near 216 to 218 g rather than 227 g. Measure solid, melt what you measured, and the gram figure carries across exactly.

One US cup of Butter (melted) is 227 g. The dataset records that as: “Same mass as solid butter”. Every ingredient on the site carries the reference its weight came from, so any number here can be checked — and corrected if the source disagrees.
