A cup is a volume and a gram is a weight, so converting between them needs to know what is in the cup. A cup of flour is about 125 g and a cup of honey about 340 g: nearly three times as heavy for the same volume.

About the Cooking Measurement Converter

Cooking Measurement Converter converts between volume and weight by ingredient, because that is the only honest way to do it. A cup is a volume; a gram is a weight; and what sits between them is density, which differs enormously between ingredients.

A US cup of water weighs 237 grams. The same cup of plain flour weighs about 125 grams, of granulated sugar about 200, and of honey about 336. Any converter that offers a single cups-to-grams number is wrong for almost everything, and the error is large enough to ruin baking in particular, where ratios matter.

Flour is the worst case even with the right density, because how you fill the cup changes the answer. Scooped straight from the bag and packed down, a cup can hold twenty per cent more than spooned in and levelled off. That variation is the real argument for weighing: a recipe in grams is reproducible and a recipe in cups is an approximation, which is why professional baking recipes are written by weight.

The page shows its working, not just its answer. Where there is a formula it is printed with your own numbers substituted in, so you can check the result rather than take it on trust -- which is the difference between a calculator you can use for something that matters and one you cannot.

Everything runs inside your browser. What you type is never uploaded, never logged and never stored, and the calculator keeps working if your connection drops after the page has loaded.

Frequently asked questions

How many grams in a cup?

It depends entirely on the ingredient. Water is 237 g, flour about 125 g, sugar about 200 g and honey about 336 g, all for the same US cup.

Which cup is this?

The US customary cup, 236.59 ml. A metric cup is 250 ml and an imperial cup was 284 ml, so check which your recipe means.

Why does flour vary so much?

Because how it is packed changes its density. Scooping and packing can add twenty per cent over spooning and levelling, which is why weighing is more reliable.
