# Measuring cups to grams converter

Converts recipe volumes to grams and ounces using per-ingredient USDA densities, across five cup sizes, spoons, and kitchen fractions.

Enter an amount to weigh it.

The densities are USDA reference weights for one US cup, and they are only as honest as your scoop. Flour in particular swings 10 to 20 percent either way depending on how hard you pack the cup, so treat the gram figure as a starting point and weigh once with your own flour to calibrate. This runs entirely in your browser; nothing is uploaded, and the ingredient table ships with the page. It does not scale recipes, substitute ingredients, or handle baking powder-style leaveners where a pinch changes the chemistry, not just the weight.
