About Grams To Cups

What this site does

Grams To Cups converts baking ingredient weights into cup measures and back again. Instead of a single generic formula, each ingredient has its own grams-per-cup density, so 100 g of flour and 100 g of sugar correctly give different cup amounts.

Where the numbers come from

Our densities are mid-range values compiled from standard American baking references and checked against manufacturer packaging. Each one is published openly on the density data page so you can see exactly what a result is based on.

How we keep it usable

• Every result also shows the nearest practical cup fraction.
• The recipe parser converts an entire ingredient list in one paste.
• Charts are printable, so you can keep one in the kitchen.
• No sign-up, no paywall, and the tools work offline once loaded.

Accuracy and feedback

Volume measuring is inherently approximate — packing flour differently can change a cup by 15%. For critical bakes, weigh. If you spot a density that looks wrong for your region, let us know and we will review it.
