Frequently asked questions
Why does 1 cup of flour and 1 cup of sugar weigh different amounts?
Cups measure volume, not weight - denser ingredients like sugar weigh more per cup than lighter ones like flour.
How much does a stick of butter weigh in this converter?
A standard US stick of butter is 1/2 cup, which converts to about 113.5g - half of the 227g-per-cup figure this calculator uses.
Why does the type of flour affect its weight per cup?
How densely the flour is packed into the measuring cup - and differences between flour types like all-purpose, bread, or cake flour - both affect weight per cup, which is why professional recipes often specify weight rather than cup measurements for consistency.
How many grams are in a cup?
It depends on the ingredient - a cup of flour is about 120g, a cup of granulated sugar is about 200g, and a cup of butter is about 227g, since cups measure volume and grams measure weight. Choose your ingredient above for the exact figure.
Is '1 cup in grams' or '1 cup to g' the same question as 'cup to grams'?
Yes - all of these ask the same thing: how many grams are in one cup of a given ingredient. Enter 1 in the cups field and pick your ingredient above for the exact figure.
Is '1 cups to grams' (plural) different from '1 cup to grams'?
No - it's the same question with a grammar slip. Enter 1 in the cups field above for the answer either way.
Is a 'cup to gram calculator' the same as this tool?
Yes - that's exactly what this calculator does. Choose your ingredient and enter a number of cups above to get the equivalent weight in grams.
Is 'cups to grams' without a number the same question?
Yes - it's asking for the same conversion, just without specifying an amount. Enter however many cups you have above (1, 2, 0.5, etc.) to get the exact grams for your ingredient.
How many cups are in a certain number of grams?
Divide the gram amount by the grams-per-cup figure for your ingredient - 240g of flour, for example, is 240 ÷ 120 = 2 cups. This calculator converts cups to grams directly; for grams to cups, divide your gram amount by the per-cup weight shown for your ingredient above.
A cup is how many grams?
It depends entirely on the ingredient, since a cup measures volume and grams measure weight - select your ingredient above (flour, sugar, butter, or brown sugar) to see its specific grams-per-cup figure.
How many grams is 1/2 cup?
Enter 0.5 in the cups field above - for example, 1/2 cup of flour is about 60g, while 1/2 cup of butter is about 113.5g, since the per-cup weight varies by ingredient density.
How many grams are in 1 1/2 cups of sugar?
About 300g for granulated sugar - enter 1.5 in the cups field with sugar selected above (200g per cup × 1.5 = 300g).
How many grams is 2 1/2 cups?
It depends on the ingredient - enter 2.5 in the cups field above with your ingredient selected. For flour that's about 300g, and for sugar it's about 500g, since the per-cup weight varies by density.
How many grams is 3/4 cup?
Enter 0.75 in the cups field above with your ingredient selected - for flour that's about 90g, and for sugar it's about 150g.
How many grams is 1 cup, in general?
There's no single answer without knowing the ingredient - it ranges from about 120g (flour) to 227g (butter) per cup for the ingredients this calculator covers, since denser ingredients pack more weight into the same volume.
Why do recipes from different countries use different measurement systems?
The US primarily uses volume-based cup and spoon measurements, while most of the rest of the world uses weight-based metric measurements (grams), which are more precise for baking since ingredient density varies. This converter bridges the two so you can follow a recipe written in either system.
