How to convert grams to cups
Divide the weight in grams by the ingredient's grams-per-cup density. For all-purpose flour that density is 125 g per cup, so 250 g ÷ 125 = 2 cups. For granulated sugar (200 g per cup), the same 250 g is only 1¼ cups — which is why the ingredient matters more than the math.
Common gram-to-cup values
- 125 g all-purpose flour = 1 cup
- 200 g granulated sugar = 1 cup
- 227 g butter = 1 cup (2 sticks)
- 120 g powdered sugar = 1 cup
- 90 g rolled oats = 1 cup

Worked example: 250 g of all-purpose flour to cups
All-purpose flour weighs 125 g per cup. Divide 250 g by 125 = 2 cups. The same 250 g of granulated sugar (200 g per cup) is only 1¼ cups, which is why selecting the right ingredient matters more than the math.
Frequently asked questions
How many cups is 250 grams of flour?
250 g of all-purpose flour is 2 cups, because all-purpose flour weighs 125 g per US cup. Bread flour (127 g/cup) would give just under 2 cups for the same weight.
Is a US cup the same as a metric cup?
No. A US cup is 240 ml; a metric cup (used in Australia and New Zealand) is 250 ml. This converter uses the US 240 ml cup, which is what most American recipes mean.
Why does my cup of flour weigh more than 125 g?
Scooping flour with the cup compacts it, so a scooped cup can reach 140–150 g. Spoon flour into the cup and level it off with a knife to match the 125 g density used here.
Can I convert grams to cups for butter?
Yes — select butter (227 g per cup). For sticks and tablespoons too, the dedicated butter converter is faster and shows every equivalent at once.
What does the result snap to fractions mean?
Cup results are rounded to common measuring-cup fractions like ¼, ⅓ and ½ so you can actually measure them. Use the swap button to flip back to grams for an exact weight.
Does this work for liquids like milk and oil?
Yes. Milk is about 245 g per cup and vegetable oil about 218 g per cup. For pure volume conversions, the grams-to-milliliters tool may be more appropriate.
