Volume to weight, with the density that actually applies

A cup of flour and a cup of honey weigh very different amounts. Pick the ingredient and convert cups, tablespoons, millilitres and grams properly.

This is the conversion most kitchen charts get wrong. A cup measures volume, a gram measures mass, and the bridge between them is density — which changes completely depending on what is in the cup.

A cup of water is 240 g. The same cup holds about 127 g of flour and roughly 341 g of honey. Choose the ingredient first and the numbers stop fighting you.

How to use

Choose the ingredient — it decides how many grams fit in a cup.
Enter the amount and the unit you are converting from: grams, millilitres or US cups.
Choose the unit you are converting to — the result appears straight away.

Grams in a cup

The cup here is 240 ml, the size used on American nutrition labels (the customary measuring cup is 236.59 ml), and it holds 240 g of water. Everything else depends on density: 127 g of flour, under 100 g of oats, 341 g of honey.

100 grams in cups

European recipes need the reverse. 100 g of flour is almost 0.8 of a cup, 100 g of sugar half a cup.

What to keep in mind

Uses the 240 ml cup from American nutrition labelling; the customary measuring cup is 236.59 ml. Metric cups (250 ml) and UK cups differ.
Flour weight depends on how it gets into the cup: scooped straight from the bag it packs down and weighs more than when spooned in and levelled.

FAQs

How many grams is one cup of flour?

About 127 g in a 240 ml cup at the calculator's 0.53 g/ml — USDA's 125 g per 236.6 ml US cup. Weighing is more reliable. Scooped straight from the bag it can be noticeably more, enough to make a dough dry.

How many grams of sugar in a cup?

204 g in a US cup. Brown sugar comes to 173 g if it is not packed down.

Why do American recipes use cups at all?

Volume measuring is faster and needs no scale. It works fine for liquids, where volume and weight track each other, and poorly for anything that compresses.

Is a US cup the same as a metric cup?

No. This calculator uses the 240 ml US cup; the metric cup used in Australia and elsewhere is 250 ml.

Is a tablespoon the same everywhere?

No. A US tablespoon is 14.8 ml, the metric standard is 15 ml, and an Australian tablespoon is 20 ml — a third larger, which matters for raising agents.

What if my ingredient is not in the list?

Use water or milk as a baseline for thin liquids like stock or juice; they sit within a few percent. Solids need their own density.

Worked example

Two cups of flour

Input: 2 cups → grams (flour)

Output: about 254 g

Note: Bakers who weigh instead of scoop get consistent bread precisely because this number moves around so much when measured by volume.
