Caster sugar: grams to cups
One cup of caster sugar weighs 200 grams. So 100 g is about 0.50 cup, 250 g is about 1.25 cups, and 500 g is about 2.50 cups.
1 ¼ cups
1.25 cups · 8.8 oz
Worth knowing. Caster is just finer granulated sugar, so the weight per cup is effectively the same. UK charts say 225 g because a UK cup is 250 ml, not 237 ml.
