All conversions
Every cooking conversion, in one place
Cups, grams, millilitres, fluid ounces, pounds, sticks of butter — cooking units are a mess of history. These tools convert between them, and the guides explain what each unit actually is.
Ingredient conversions
A cup is a volume and a gram is a weight, so converting between them needs the ingredient's density. One cup of flour is 120 g, one cup of sugar is 200 g, one cup of butter is 227 g. These tools convert by ingredient, using published King Arthur Baking and USDA data.

Guides that explain the units
The tools give the answer; the guides give the understanding — why a US cup and a metric cup differ, what a stick of butter weighs, and how many cups are in a can.
Cups to Grams by Ingredient
The real weight of one cup of every common ingredient, with the density data behind it.
Grams to Cups by Ingredient
Your recipe says 200 grams and you only have measuring cups — convert back, ingredient by ingredient.
Tablespoons to Grams
Small amounts matter most in baking. Tablespoon and teaspoon weights for the ingredients you measure in small amounts.
