Frequently asked questions
How many grams are in one cup of flour?
One US cup of all-purpose flour weighs approximately 125 grams. Bread flour is slightly denser at about 130 grams per cup, and cake flour is lighter at around 110 grams per cup. The exact weight depends on whether you scoop or sift the flour — sifting can reduce the weight by up to 15 percent. We use the King Arthur Flour reference values: 120 grams per cup for all-purpose flour spooned and levelled.
How many grams are in one cup of butter?
One US cup of butter is 227 grams (half a US pound, or two sticks). Half a cup is one stick, weighing 113 grams. A tablespoon of butter is approximately 14 grams.
How many grams are in one cup of sugar?
One US cup of granulated white sugar is approximately 200 grams. Brown sugar packed firmly is denser at about 220 grams per cup. Powdered (icing) sugar is much lighter at around 120 grams per cup because of the air content.
How do I convert oven temperatures from Fahrenheit to Celsius?
Common oven temperatures: 300°F is 150°C (warm), 350°F is 177°C (medium bake), 375°F is 190°C, 400°F is 204°C (hot), and 450°F is 232°C (pizza-oven hot). The exact formula is (F − 32) × 5/9 = C. For everyday cooking, rounding to the nearest 5 or 10 °C is fine.
How many tablespoons are in a cup?
One US cup contains 16 tablespoons. A tablespoon contains 3 teaspoons, so one cup is 48 teaspoons. A US cup is 236.6 millilitres, a tablespoon is 14.8 millilitres, and a teaspoon is 4.9 millilitres.
Why does the same volume of flour and sugar weigh different amounts?
Different ingredients have different densities. Flour is light and full of tiny air pockets (about 0.53 grams per millilitre), while granulated sugar is dense (about 0.85 grams per millilitre), and water is denser still (1.00 gram per millilitre). That is why volume measurements like cups are imprecise for baking — and why most professional bakers prefer to weigh ingredients in grams.
Are these conversions accurate for UK recipes?
The volume conversions on this page use US customary units (a US cup is 236.6 millilitres). UK recipes use metric units almost exclusively for cooking, but if you encounter an old British recipe that calls for cups, the British imperial cup (284 millilitres) is slightly larger. For ingredient weights, density is independent of measurement system, so the gram values are correct regardless.
