1 cup: 125g; 4.41 oz
1 tablespoon: 7.8g
1 teaspoon: 2.6g
100 g: 0.8cups; of a US cup

All-purpose flour is the default white flour in most home recipes, a blend that is neither as soft as cake flour nor as strong as bread flour. Spooning it into the cup and levelling gives a lighter result than dipping the cup into the bag, which packs it down. Because it sits between soft and strong flours, all-purpose flour is the one most recipes assume when they only say flour. If a recipe does not name a flour, this is the page to use. Weighing it takes the guesswork out of the cup, and it is the main reason many recipe writers now list grams beside cups for flour.

What a cup of all-purpose flour weighs, and why it can differ

USDA’s weight for “1 cup” is 125 g. Next to a cup of water, which holds about 236.6 g, that is 53% of the weight of a cup of water, so a lot of the cup is air. The same cup works out at 0.53 g per millilitre.

USDA lists one cup measure for all-purpose flour (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it.

USDA lists no tablespoon or teaspoon measure for this entry, so that weight is the cup weight divided by the US ratio (16 tablespoons or 48 teaspoons to the cup).

How many cups is 500 g of all-purpose flour?

500 g of all-purpose flour is 4 cups, using 125 g per cup of all-purpose flour. A 1 kg bag of all-purpose flour would fill 8 cups, and a 1 lb pack of all-purpose flour would fill 3.63.

How much does a part of a cup of all-purpose flour weigh?

Half a cup of all-purpose flour is 62.5 g, a third of a cup of all-purpose flour is 41.7 g and a quarter cup of all-purpose flour is 31.3 g. For small amounts, 1 tablespoon of all-purpose flour is 7.8 g (0.28 oz) and 2 tablespoons of all-purpose flour are 15.6 g.

If my recipe uses 250 ml metric cups, how much all-purpose flour is that?

A 250 ml cup is about 5.7% larger than a US cup, so a metric cup of all-purpose flour comes to about 132.1 g, going by USDA’s 125 g for a US cup of all-purpose flour. The weights on this page are for the US cup of about 237 ml.

Is it better to weigh all-purpose flour than to measure it by the cup?

For baking, yes. USDA lists one cup measure for all-purpose flour (“1 cup”), so this page has no second figure to compare it with; if a recipe depends on the exact amount, weigh it. Next to water, a cup of all-purpose flour is 53% of the weight of a cup of water, so a lot of the cup is air, and 125 g on a scale is 125 g however the all-purpose flour was scooped.

What weighs about the same as a cup of all-purpose flour?

Among these converters, self-rising flour (125 g per cup) and cornmeal (122 g per cup) come closest to 125 g. Same volume, different ingredient: the weights are close, but the foods are not interchangeable.
