Cooking Measurement Converter
Convert between cups, spoons, millilitres, grams and ounces — with the density of the ingredient, because a cup of flour and a cup of sugar are not the same weight.
Volume measures convert between each other exactly.
How the cooking measurement converter works
Volume measures convert between each other exactly. Converting volume to weight does not, because it depends entirely on what is in the cup: a metric cup holds 150 g of flour, 200 g of sugar, 250 g of water and 340 g of honey.
That is why professional baking works by weight. The cup measures here use standard densities, and even then how the flour was scooped changes the result by 20%.
Formula: grams = millilitres × density
Worked examples
| Inputs | In grams | Note |
|---|---|---|
| One metric cup of flour | 150 g | 150 g |
| One cup of sugar | 200 g | 200 g |
| One cup of honey | 340 g | 340 g |
FAQFrequently asked questions
How many grams in a cup?
It depends entirely on the ingredient. A metric cup holds 250 g of water, 200 g of sugar, 150 g of flour and 340 g of honey.
Why do recipes use weight?
Because volume measures of dry ingredients vary by up to 20% depending on how they were scooped. Weight removes that entirely.
Is an Australian tablespoon different?
Yes — 20 mL against the 15 mL used almost everywhere else. It is four teaspoons, not three.
Is a US cup the same as a metric cup?
No. A US cup is 236.6 mL and a metric cup 250 mL, a 5.6% difference that compounds across a recipe.
How should I measure flour by volume?
Spoon it into the cup and level it off. Scooping directly compacts it and can add 20% by weight.
