Sugar: Cups to Grams
Choose your sugar and convert cups, tablespoons or teaspoons to grams.
Brown sugar is firmly packed and powdered sugar is unsifted. Results vary by brand and how you measure.

Sugar types pack differently, so each one weighs a different amount per cup. Granulated and caster sugar are about 200 grams per cup. Brown sugar is measured firmly packed and weighs about 213 grams, while powdered sugar is much lighter at around 120 grams because it is full of air.
Use the selector to choose your sugar, then enter the amount in cups, tablespoons or teaspoons. Results appear instantly in grams and ounces. In recipes that call for packed brown sugar, press the sugar into the cup until it holds its shape when tipped out, or skip the guesswork and weigh it.

Frequently asked questions
How many grams are in a cup of granulated sugar?
About 200 g. Caster (superfine) sugar weighs about the same per cup.
Why is brown sugar heavier per cup?
Brown sugar is measured firmly packed and contains molasses, so a cup weighs about 213 g.
How many grams are in a cup of powdered sugar?
About 120 g when unsifted. Sifted powdered sugar is lighter, so weighing it is more consistent.
Can I swap granulated sugar for brown sugar one to one?
By weight, usually yes, but brown sugar adds moisture and a caramel flavor, so the texture and color of the result will change.
