Cups to mL: Butter
Convert cups to milliliters for any ingredient, using real densities rather than a single average — flour, sugar, butter and honey all fill a cup differently for butter specifically.
The density that makes this specific
One US cup of butter weighs about 227 g, measured by spooning it into the cup and levelling the top. That figure is what this page converts with — a cup of sugar (200 g) or honey (340 g) would give a completely different answer from the same volume.
Scooping the cup directly into the container compacts the contents and can add 20% or more, which is why the same recipe can behave differently in two kitchens. If you own a scale, weigh it.
Why the ingredient matters
This conversion crosses between volume and weight, so it depends on density. A US cup of all-purpose flour is 125 g; the same cup holds 200 g of granulated sugar and 340 g of honey. Pick the ingredient above and the factor changes with it.
