Cooking Conversion Calculator

When you convert between volume (cups, tablespoons) and weight (grams, ounces), the result depends on the ingredient's density. For example, 1 cup of all-purpose flour weighs 125g while 1 cup of honey weighs 340g. Our calculator includes density data for 40+ common cooking ingredients so you get accurate conversions every time.

Enter the original number of servings your recipe makes, then enter how many servings you want. Add each ingredient with its amount and unit. The calculator automatically multiplies every ingredient by the correct ratio. For example, scaling from 4 servings to 6 multiplies everything by 1.5×.

Gas Mark is a temperature scale used on gas ovens, primarily in the UK and some Commonwealth countries. Gas Mark 1 equals 275°F (135°C), and each mark increases by about 25°F (14°C). Common baking temperatures: Gas Mark 4 = 350°F (177°C), Gas Mark 5 = 375°F (191°C), Gas Mark 6 = 400°F (204°C).

A US cup equals 236.588 ml, while a metric cup (used in Australia and some other countries) equals 250 ml. This calculator uses US cups by default, as they are the standard in most English-language recipes. The difference of about 13ml can matter in precise baking, so always check which cup standard your recipe uses.

Volume-to-weight conversions for dry ingredients like flour and sugar can vary by 10-15% depending on how you measure. Scooping flour directly from the bag compacts it, giving a heavier cup (up to 150g) versus the spoon-and-level method (125g). Our values use the spoon-and-level method, which is the standard referenced by most cookbook authors. For best accuracy, use a kitchen scale.
