Why Cups to Grams Matters

A cup of flour can weigh anywhere from 120 to 150 grams depending on how you measure it. That's a 25% difference — enough to ruin a cake. Professional bakers measure by weight because it's precise, consistent, and reproducible.

This calculator uses verified ingredient densities from USDA and King Arthur Baking sources. Every conversion accounts for the specific density of each ingredient, not a generic "1 cup = 240g" approximation.

US Cup vs Metric Cup vs Imperial Cup

Not all cups are the same size:

US Customary Cup = 236.59 mL (most American recipes)
Metric Cup = 250 mL (Australia, New Zealand, Canada)
Imperial Cup = 284.13 mL (older British recipes)

Every calculator on this site lets you switch between cup standards for accurate results no matter which recipe you're following.
