Sugar here means standard white granulated sugar, the everyday sweetener used in cakes, biscuits, sauces, and drinks. One metric cup (250 ml) of granulated sugar weighs around 200 grams or 7.05 ounces. When a recipe lists sugar in cups but you only have kitchen scales, converting by weight keeps the sweetness and structure right.

Granulated sugar settles differently depending on how you scoop and level the cup, so weighing in grams gives more consistent results than volume alone. This page converts sugar between grams, cups, tablespoons, and more for any recipe.

Caster sugar is more finely milled than granulated sugar, so it dissolves faster and is the better choice for meringues and delicate sponges. They are close in weight (225 g vs 200 g per cup); swap 1:1 by volume in most recipes. See our Caster Sugar converter.

Brown sugar contains molasses, adding moisture and a caramel flavour that granulated sugar lacks. Packed, it weighs more by cup (220 g vs 200 g), so weigh it when swapping to keep the sweetness and texture on track. See our Brown Sugar converter.

Icing sugar is granulated sugar ground to a powder, used for frostings and dusting rather than creaming into batters. It packs lighter (125 g vs 200 g per cup), so the two are not a straight 1:1 swap. See our Icing Sugar converter.

Raw sugar is a coarser, less refined cane sugar with larger crystals and a faint molasses taste. It weighs about the same per cup (200 g each) and swaps 1:1 by volume, adding crunch and a subtle caramel note. See our Raw Sugar converter.
