300 Grams to Cups
300g = 2.4 cups of all-purpose flour, 1.5 cups of granulated sugar, or 1.32 cups of butter
There is no one answer, and any page that gives you one is guessing. A gram is a weight and a cup is a volume, so 300g of a light ingredient fills far more of a cup than 300g of a dense one. Pick your ingredient below, or read the full chart for all 17.

Why 300 grams is not a single number of cups
Cups measure the space an ingredient takes up. Grams measure how much matter is in it. The bridge between them is density, and density changes with every ingredient — which is why 300g of all-purpose flour comes to 2.4 cups while the same 300g of butter is only 1.32 cups.
The spread on this page is wide. 300g fills 3.53 cups of cocoa powder at one end and 0.88 cups of honey at the other. Using the wrong one is the difference between a cake that rises and a cake that does not, which is exactly why recipes written outside the US give weights in the first place.
How to convert 300 grams to cups yourself
Divide the weight by what one cup of that ingredient weighs:
cups = 300 ÷ grams per cup
For all-purpose flour, one cup is 125g, so 300 ÷ 125 = 2.4 cups. For granulated sugar at 200g per cup, 300 ÷ 200 = 1.5 cups. Going back the other way, multiply instead of dividing.
One caveat worth knowing: the grams-per-cup figures above assume flour is spooned into the cup and levelled, not scooped and packed. Scooping straight from the bag compresses it and can add 20–25% more weight, so a scooped cup of flour is closer to 150g than 125g. If your results keep coming out heavy, that is usually why. Brown sugar is the opposite convention — it is measured packed, which is already reflected in its figure.
Other weights to cups
| Weight | All-purpose flour | Granulated sugar | Butter |
|---|---|---|---|
| 200g | 1.6 cups | 1 cups | 0.88 cups |
| 250g | 2 cups | 1.25 cups | 1.1 cups |
| 300g | 2.4 cups | 1.5 cups | 1.32 cups |
| 500g | 4 cups | 2.5 cups | 2.2 cups |

300 grams to cups: common questions
How many cups is 300 grams?
It depends on the ingredient. 300g is 2.4 cups of all-purpose flour, 1.5 cups of granulated sugar and 1.32 cups of butter. The table above covers 17 of them.
Is 300 grams the same in US and metric cups?
No. The figures here use the US cup of 240ml, which is what US recipes mean. A metric cup is 250ml and an imperial (UK) cup is 284ml, so the same 300g fills slightly less of those. The cup sizes guide has the full comparison.
Should I convert at all?
If you own a scale, no. Weighing is faster and more accurate than levelling cups, and it is why every professional kitchen works in grams. Convert when the recipe gives grams and you only have cups — not the other way round.
