In American measures, a half-cup is equal to one-fourth of a pound of butter. This translates to 0.42 cups, or 118.29 millilitres, in the British Imperial system of measures. A stick of butter that weighs a quarter pound is how it is packaged and sold in the US.
In contrast to many American recipes, cooks in other countries do not measure butter by the stick. Instead, they weigh butter on a kitchen scale to quantify it. An American cookbook’s measurements are converted to 113.4 grammes for a stick of butter. Butter is frequently offered for sale in boxes of four sticks, or one pound, or 453.6 grammes, in the United States.
