FAQ

How many grams is 1 cup of all-purpose flour?

About 125 grams per US cup when spooned and leveled. Scooping from the bag can pack closer to 140–150 g — weighing removes the guesswork.

How many grams is 1 cup of sugar?

Granulated white sugar is about 200 g per cup. Packed brown sugar is about 220 g. Powdered (icing) sugar is lighter at ~120 g per cup.

How many grams is 1 cup of butter?

One US cup of butter is 227 g (2 sticks). Half a cup is 113 g (1 stick).

Why do free cups-to-grams converters disagree?

They use different density assumptions and packing methods. CookBank uses the same density table as the CookBank app (500+ ingredients) so web and app stay consistent.

Can I convert grams to cups?

Yes. Switch the unit to grams or ounces and the tool shows cups (and tablespoons when useful) for that ingredient.

Is a US cup the same as a metric cup?

No. A US cup is 236.588 ml; a metric cup is 250 ml. This tool uses US cup density values common in US recipes.

Is this cups to grams converter free?

Yes — free in the browser, no account. Photo recipes, full libraries, and grocery sync live in the CookBank app.
