How to measure it

Granulated sugar is the best behaved ingredient in the kitchen. Its crystals are heavy, uniform and free flowing, so a cup weighs 200 g whether you scoop it, pour it or spoon it. There is no packing method to argue about.

That reliability makes sugar a good sanity check for the rest of a chart. If a conversion table lists granulated sugar far from 200 g a cup, treat its other numbers with suspicion too.

Caster or superfine sugar weighs almost the same per cup. Coarse sanding sugar sits a little heavier, and you should weigh it if precision matters.

Density source: Published baking company ingredient charts. Method assumed: Granulated sugar barely compresses, so this number holds.

Questions about granulated sugar

How many cups is 250 g of sugar?

1.25 cups, or one cup plus a quarter cup. Granulated sugar is consistent enough that this holds regardless of how you fill the cup.

Is caster sugar the same conversion as granulated?

Close enough for baking. Caster sugar runs about 195 to 200 g a cup, so you can use the same 200 g figure without noticeable error.
