Cups to grams

1 Cup Sugar in Grams

1 cup of sugar weighs:

200g

US cup (240 ml)

208g

Metric / AU cup (250 ml)

American recipes mean the 240 ml cup; Australian, British and New Zealand recipes mean the 250 ml metric cup. If the recipe does not say, the cuisine usually tells you — see the full cups to grams guide.

Granulated and caster sugar both come in at about 200 g per US cup. Sugar is far more forgiving to measure than flour — the crystals do not compress the way flour does, so a scooped cup and a levelled cup weigh nearly the same.

Questions

Frequently asked questions

How many grams is 1 cup of sugar?
1 US cup of sugar is 200 g. In an Australian, UK or NZ metric cup (250 ml) it is 208 g. Weighing is more accurate than measuring by volume.
How many grams is half a cup of sugar?
Half a US cup of sugar is 100 g, and three-quarters of a cup is 150 g.
Is caster sugar the same weight as granulated sugar?
Yes, for practical purposes. Both are about 200 g per cup. Caster sugar has finer crystals so it dissolves faster, but the packing density is close enough that recipes swap them by volume without adjustment.
Does brown sugar weigh the same as white sugar?
No — brown sugar is packed into the cup, which makes it denser at about 220 g. Recipes calling for brown sugar almost always mean firmly packed.
Do I need to level a cup of sugar?
It helps, but sugar is much less sensitive than flour. A heaped cup might add 10–15 g rather than the 25 g a heaped cup of flour adds.
