300 Grams of Sugar to Cups
1½ cups in a US cup — and what that looks like with a measuring spoon
300 grams of granulated sugar is 1½ cups in a US cup. In the kitchen that is 1½ cups.
Grams weigh and cups fill, so the answer only exists once you say what is in the cup. A US cup of granulated sugar weighs 200 g, and every figure on this page comes from that one number.
It also depends on whose cup you mean. In a 250 ml metric cup — the standard in the UK, Australia, New Zealand and Canada — 300 g of granulated sugar is 1⅜ cups, because that cup holds about 5.7% more than the 236.6 ml US cup.
That lands exactly on the 1½ cups measure, so no rounding is needed.
300 g of sugar in each cup standard
| Cup standard | Size | Grams per cup | Cups |
|---|---|---|---|
| US customary | 236.6 ml | 200 g | 1½ |
| Metric (UK, AU, NZ, CA) | 250 ml | 211 g | 1⅜ |
| Imperial (older UK) | 284 ml | 240 g | 1¼ |
A recipe that says "cups" without saying which one is almost always American. If it came from a British, Australian or New Zealand source, use the metric row.
How to measure 300 g of sugar without scales
Granulated sugar does not compact the way flour does, so scooping and spooning give almost the same weight. Fill the cup and level it off.
This is white granulated sugar at 200 g per cup. Caster sugar is finer and packs to 225 g, and powdered sugar is much lighter at 120 g, so those are different conversions.
- Build it as 1½ cups rather than guessing at 1½ of a cup.
- 300 g is 24 tablespoons of granulated sugar, at 12.5 g per tablespoon.
- A digital scale removes the question entirely, and costs less than the ingredients it saves.

Is 300 g of sugar the same in cups in the UK?
No. A UK, Australian, New Zealand or Canadian metric cup is 250 ml against the US cup's 236.6 ml, so 300 g of granulated sugar is 1⅜ cups there and 1½ cups in the US.
