Cups to Grams
The cups to grams converter turns cups into grams for flour, sugar, butter, and other ingredients, and works the same way in reverse. Cups measure volume and grams measure weight, so the result depends on the ingredient — this page uses all-purpose flour at 120 g per cup, and you can switch ingredient in the calculator.
Cups are volume and grams are weight, so the result depends on the ingredient. Pick yours below — the default is all-purpose flour.
Ingredient weights come from the King Arthur Baking ingredient weight chart; water and other liquids use 1 gram per millilitre.

Frequently asked questions
How many grams are in 1 cup?
There are 120 g in 1 cup of all-purpose flour. The table on this page lists the everyday amounts, and the calculator converts any value the moment you type it. That figure is specific to all-purpose flour: cups measure volume and grams measure weight, so a lighter or denser ingredient gives a different number.
How do you convert cups to grams?
To convert cups to grams, enter the amount in the cups box and the grams result appears instantly; type in either box to convert both ways. Because all-purpose flour is measured by volume but weighed in grams, this uses all-purpose flour's density of 120 g per cup from the King Arthur Baking ingredient weight chart. The conversion table above covers 0.25 to 3 cups if you would rather read a value off than type one. Nothing is rounded until the result is displayed, so part-amounts convert as exactly as whole ones.
Is this cups to grams converter free?
Yes — this cups to grams converter is completely free, with no sign-up and no limit on how many conversions you run. Every calculation runs locally in your browser, so nothing you type is uploaded. For every unit and ingredient in one place, use the full cooking and baking converter.
Does the ingredient change the cups to grams result?
Yes — the ingredient changes the cups to grams result, because volume and weight are not the same quantity. On the King Arthur Baking ingredient weight chart a cup of all-purpose flour weighs 120 g, a cup of granulated sugar weighs 198 g and a cup of old-fashioned oats weighs 89 g — one volume, three very different weights. This page is set to all-purpose flour at 120 g per cup, and the ingredient menu in the calculator switches it. Never reuse one ingredient's figure for another.
