How many cups is 200 grams of granulated sugar?

Granulated white sugar has a standard density of 200 g per US cup, so 200 grams equals exactly 1 cup.

How many cups is 100 grams of powdered sugar?

Powdered (confectioners) sugar is much lighter and fluffier, measuring approximately 120 g per cup. So 100 grams of powdered sugar is about 0.83 cups, or roughly 13 tablespoons.

Why does brown sugar weigh more per cup than granulated?

Brown sugar is measured packed into the cup, which compresses the crystals and molasses coating together. Packed light or dark brown sugar weighs approximately 220 g per cup, compared to 200 g for loose granulated sugar.

Is light brown sugar the same density as dark brown sugar?

Yes. Both light and dark brown sugar are packed when measured, and the density is essentially the same at about 220 g per cup. The difference is the amount of molasses, which affects flavor and color but not weight.

Can I use this converter for coconut sugar or caster sugar?

Coconut sugar and caster (superfine) sugar are both close to 200 g per cup, so the granulated setting gives a good approximation. For best precision with specialty sugars, always weigh on a kitchen scale.

How do I convert grams of sugar to tablespoons?

There are 16 tablespoons in a US cup. Once you know the cup amount from this converter, multiply by 16 to get tablespoons. For granulated sugar, 1 tablespoon is about 12.5 g.

Sugar type	g / cup
Granulated white	200 g
Powdered / confectioners	120 g
Light brown, packed	220 g
Dark brown, packed	220 g

Tip: Brown sugar is always measured packed. Spoon it firmly into the cup until it holds the shape of the cup when turned out. Powdered sugar should be spooned in lightly — do not pack or sift unless the recipe specifies.
