Granulated Sugar: Cups to Grams
One US cup (240 ml) of granulated sugar weighs 200 grams; half a cup weighs 100 grams. A quarter cup is 50 grams, a tablespoon is 12.5 grams and a teaspoon is 4.17 grams. A cup measures volume, not weight, so these numbers are for granulated sugar only: a cup of all-purpose flour weighs 125 grams.
200 g
1 cup of granulated sugar = 200 g (US legal cup, 240 ml)

Ounces here are ounces of weight (1 oz = 28.35 g), not fluid ounces. One US cup is 8 fluid ounces of volume whatever is in it, but what it weighs in ounces depends on the ingredient: a cup of granulated sugar weighs about 7.05 oz. Why these two are not the same. Decimals for thirds are rounded (1/3 cup is 0.333 cups), and each linked amount opens a page comparing every ingredient at that measure.

About measuring granulated sugar
Granulated white sugar is dense and free-flowing, so it is one of the more predictable ingredients to measure by volume. One US cup weighs about 200 grams. Unlike flour it does not compress much, so a scooped cup and a levelled cup come out close. Still, weighing pays off in recipes where the sugar-to-flour ratio controls texture, like cookies that should spread just so or a caramel that needs the right balance.
Sugar barely compresses, so a scooped cup is close to a levelled one, but weighing is still safest.
How many grams is a cup of granulated sugar?
One US cup (240 ml) of granulated sugar weighs about 200 grams. Because a cup measures volume rather than weight, that figure is specific to granulated sugar and does not transfer to any other ingredient: the same cup holds 125 grams of all-purpose flour and 340 grams of honey.
- 1/4 cup of granulated sugar is about 50 grams
- 1/3 cup of granulated sugar is about 67 grams
- 1/2 cup of granulated sugar is about 100 grams
- 2/3 cup of granulated sugar is about 133 grams
- 3/4 cup of granulated sugar is about 150 grams
- 1 1/2 cups of granulated sugar is about 300 grams
- 2 cups of granulated sugar is about 400 grams
- 3 cups of granulated sugar is about 600 grams
Working the other way round, 100 grams of granulated sugar is about 0.5 cups, and 500 grams is about 2.5 cups.
Does it matter which cup my recipe means?
It does, though less than the ingredient itself. This page uses the US legal cup of 240 ml. An Australian metric cup is 250 ml, so a metric cup of granulated sugar comes to about 208 grams, and the old British imperial cup of 284.1 ml holds about 237 grams. See cup sizes by country for every standard side by side.
Frequently asked questions
How many grams is 1 cup of granulated sugar?
One US cup of granulated white sugar is about 200 grams. It is dense and does not pack down much, so cups are fairly consistent.
Is caster sugar the same weight as granulated?
Very nearly. Caster (superfine) sugar has smaller crystals that settle a little tighter, so a cup can run slightly heavier, but 200 grams is a safe working figure.
How many grams is a tablespoon of sugar?
About 12.5 grams. There are 16 tablespoons in a cup, so 200 grams divided by 16 gives you roughly 12.5 grams per tablespoon.
Where this figure comes from
We have not yet found a published reference that states a weight for a cup of granulated sugar. The 200 grams on this page follows the calibration the rest of the site is built on, with butter at 227 grams per cup, water at 240, all-purpose flour at 125 and granulated sugar at 200. Treat it as a good working figure rather than a cited one. If you have a better source, tell us and we will check it and credit you.
Published figures for the same ingredient vary between references anyway, because how an ingredient is packed changes what a cup of it weighs. Treat any cup figure as accurate to within a few percent, and weigh on a scale when a recipe is sensitive. Our full approach is on the methodology page.
