There are two cups of butter in a pound. This is an industry-standard dairy measure that can be generally relied upon by cooks and bakers across the United States.
If a recipe that calls for one pound of butter and no scale is available, measuring out two cups is a reliable substitute. The dairy industry in the United States uses standard measurements, making it easy for cooks and bakers to ensure their recipes turn out right. One pound of butter can also be measured as four standard sticks of butter. This may be different in other nations, but it is a reliable constant in the USA.
