Cups to grams, ingredient by ingredient
A cup of flour and a cup of sugar don't weigh the same. Pick the ingredient and get the weight, using published densities for over a hundred of them.
1 cup all-purpose flour, spooned & levelled is about
125g
- 4.41 oz
- 16 tbsp
- 237 ml
Weights are rounded to whole grams under 50 g, then to the nearest 5 or 10 g. Density from USDA FoodData Central.
How to use it
Type the amount and unit from your recipe, then search for the ingredient. If the way you measure it matters (flour scooped or sifted, brown sugar packed), choose that too. Recipes from Australia, New Zealand or Canada use a 250 ml metric cup: switch the cup size to match.

Why a cup of flour isn't a fixed weight
A cup measures space, not stuff. How much flour fills that space depends on how fine it is and how you got it into the cup: spoon it in gently and level it and you'll get about 125 g; dig the cup into the bag and pack it and you can get 140 g or more. That's a 10–15% difference before you've done anything else, which is enough to turn a soft cake dry.
Weighing removes the guesswork, which is why bakers swear by a digital scale. When a recipe only gives cups, converting to grams with the right density for the ingredient is the next best thing.
Questions
How many grams are in a cup of flour?
About 125 g for all-purpose (plain) flour, spooned into the cup and levelled. Scooped straight from the bag it can be 140 g or more, which is why bakers weigh.
Is a UK or Australian cup the same as a US cup?
Not quite. A US cup is 236.6 ml; the metric cup used in Australia, New Zealand and Canada is 250 ml, so it holds about 6% more. Switch the converter to "metric cup" for recipes from those countries.
Why can't I convert milk or oil to grams here?
Liquids are measured by volume in recipes, so the converter gives you the volume in ml instead. For water, 1 ml weighs 1 g.
