Cooking from both US and UK recipes? One lists cups, the other lists grams — and a cup of flour weighs nothing like a cup of honey. This free converter translates cups to grams (and back again) for 10 everyday baking ingredients, fractions like 1/2 and 1 1/2 included, so your bakes turn out right every time.
No need to press anything — the result updates automatically as you type.

Cups & grams: quick answers
Why does 1 cup weigh differently for different ingredients?
A cup measures volume, not weight. Dense ingredients like honey (340 g per cup) pack far more mass into the same space than light, airy ones like flour (125 g per cup) — so every ingredient needs its own conversion.
Can I enter fractions like 1/2 or 1 1/2?
Yes. Type fractions (1/2, 3/4), mixed numbers (1 1/2) or decimals (0.75) — the converter understands them all. The quick chips under the amount field work too.
How do I convert grams back to cups?
Tap the “Grams → Cups” tab, enter the weight in grams, and you’ll get the matching cup amount — shown as a handy fraction like 1 1/2 where it fits.
How accurate is this converter?
Values are standard US-cup weights, rounded to the nearest 0.1 g — plenty accurate for everyday baking. For competition-level precision, weigh ingredients on a kitchen scale.
Do I need an account to use it?
