Cups to Grams: Stop Guessing, Start Weighing

Convert recipe ingredients between weight and volume (cups, grams, oz).

Approximate conversion between cups (volume) and grams (weight) for common ingredients. Density varies by brand and packing.

Ever try to measure a cup of flour? It's a mess. One day it's 120g, the next it's 140g depending on how you packed it. That's why professional bakers weigh everything. This tool converts those vague 'cups' into precise grams so your cookies actually turn out right.

What Does This Tool Do?

This is a density calculator. Since a cup of sugar weighs a lot more than a cup of flour, you can't just use a standard conversion number. We've programmed in the density for common ingredients so you can switch between volume (cups/spoons) and weight (grams) instantly. It's the quickest way to fix a recipe that doesn't use your preferred units.

How to Use It (Step-by-step)

1

Pick your ingredient (flour, sugar, butter, etc).

2

Type in the amount you have (like '1.5' or '1/2').

3

Tell us if that's cups or grams.

4

Boom. There's your conversion.

Key Features

  • Smart conversions based on ingredient density (because feathers don't weigh the same as lead).
  • Covers the basics: flour, sugar, butter, oil, milk, and more.
  • Works offline once loaded (great for spotty kitchen Wi-Fi).
  • Simple, no-nonsense interface.

Use Cases

  • Baking with a scale (which you should be doing!).
  • Translating a US recipe for a European kitchen (or vice versa).
  • Double-checking if that '1 cup' of chopped walnuts is actually enough.

FAQ

Because of air! A cup of water is about 240g, but a cup of flour is full of air pockets, so it's only about 120g. If you used 240g of flour, you'd be making a brick, not a cake.
For cooking (soups, stews)? Nah, close enough is fine. For baking? Yes. Chemistry cares about grams.
We've got you covered. Milk, oil, water—they all have slightly different weights, and we handle the math.
