Tips
Sugar is one of the more consistent cup measurements. No need to pack — just level off.
Cup measurements can vary by up to 20% depending on how you fill the cup. For consistent baking results, weighing ingredients in grams is always more accurate.
How Much Does a Cup of Sugar Weigh?
1 US cup of granulated sugar = 200 g. Powdered/icing sugar = 110-120 g (lighter). Brown sugar (packed) = 215-220 g (compressed). Caster sugar (UK) = 200 g. The granulated sugar value is the most common in recipes - 'cup of sugar' almost always means granulated unless specified otherwise.
Cups of sugar convert more reliably than cups of flour because sugar particles pack uniformly. The 200 g/cup figure is consistent across most US baking sources. UK metric cups (250 ml) hold ~210 g. Always pack brown sugar into the cup for accurate weight - sugar cookies and cake recipes assume packed brown sugar.

Frequently Asked Questions
Is brown sugar always packed?
Almost always in baking recipes. 'Packed brown sugar' is the default - press it firmly into the measuring cup so it holds the cup shape when turned out. Loose brown sugar measures about 165 g/cup vs 215 g packed.
Are caster sugar and granulated sugar interchangeable?
Mostly yes for measuring purposes (similar weight per cup). The texture difference matters in some applications - caster sugar's finer grains dissolve faster (better for meringues, syrups). Granulated works fine in most recipes despite slightly slower dissolving.
