1 cup (US) in every unit
A US cup is 236.6 ml, a metric cup is 250 ml and a UK tablespoon is larger than a US one — so the system your recipe was written in matters. Pick the matching unit rather than assuming.
Cups to grams by ingredient
Volume converts on its own, but weight depends on what you are measuring. These pages give the grams per cup for each ingredient.
How to use
- Enter your amount — the quantity exactly as the recipe gives it.
- Choose the unit it is written in. US and metric cups are separate entries, because a US cup is 236.6 ml and a metric cup is 250 ml.
- Choose what you want it in. The result appears instantly, with the nearest measuring-cup fraction where there is one.
- Or just read the table. Every unit is listed at your amount, so you rarely need to change the target at all.
Questions
How many dl is one cup?
A US cup is 2.37 dl and a metric cup is exactly 2.5 dl. Most American recipes mean the US cup; Scandinavian and Australian recipes normally mean the 250 ml metric cup.
Which cup does my recipe mean?
American recipes use the US customary cup (236.6 ml). Australian, and most metric recipes, use a 250 ml cup — about 6% larger. Both are in the list, so pick the one matching where the recipe came from.
Is a UK tablespoon the same as a US one?
No. A UK tablespoon is 17.76 ml against 14.79 ml for the US, and many modern European recipes use a flat 15 ml metric spoon. Across several spoonfuls the difference adds up.
Can I convert cups to grams here?
Not directly, because that depends on the ingredient — a cup of flour is 120 g while a cup of honey is 340 g. The per-ingredient pages linked below give the weight for each one.
