About this tool

A cup of flour and a cup of sugar do not weigh the same, so a plain unit converter gives the wrong answer for baking. This calculator uses an average weight for each common ingredient, such as 120 g for a US cup of plain flour and 200 g for granulated sugar, and converts between cups, tablespoons, teaspoons, grams and ounces. Weighing with scales is more accurate than cups, so use the grams where you can.
