Frequently asked questions
How many grams in a cup of flour?
One US cup of all-purpose flour weighs about 120 g (4.25 oz) when scooped and leveled correctly. Spooning flour into the cup (instead of scooping with the cup) gives a more accurate weight — direct scooping packs flour and can land between 130 and 150 g. King Arthur and most American baking blogs standardize on 120 g/cup; Cook's Illustrated uses 142 g/cup.
Is a UK tablespoon the same as a US tablespoon?
No. A US tablespoon is 14.79 mL (3 US teaspoons). A UK / Imperial tablespoon is 17.76 mL (the same as the Imperial fluid ounce divided by 1.6). An Australian tablespoon is 20 mL — even more different. For small quantities like baking-powder, the difference can throw off chemistry. Use a kitchen scale or convert through a known mL value when adapting recipes between countries.
How can I measure flour without a scale?
Use the spoon-and-level method: stir the flour in its container to aerate it, spoon it lightly into a dry measuring cup until heaping, then level the top with the flat side of a knife — never tap the cup or pack the flour. This lands within ±5 g of the standard 120 g/cup. For higher precision, a $15 digital scale pays for itself the first time it saves a batch of cookies.
