Cups to Grams Calculator
Convert cups to grams for your favorite cooking and baking ingredients. Since different ingredients have different densities, one cup of flour weighs much less than one cup of honey. Pick your ingredient and get an accurate weight.
Measuring ingredients by weight (grams) instead of volume (cups) is the secret to consistent baking. A cup of flour can vary by 20-30% depending on whether you scooped it, spooned it, or sifted it. Weight doesn't change.

Pro Tip: When a recipe gives both cups and grams, always use the gram measurement. It's what the recipe developer actually tested with. The cup measurement is often a rounded approximation.
One US cup = 236.588 mL = 16 tablespoons = 48 teaspoons. Note that US cups, UK cups (284 mL), and metric cups (250 mL) are all slightly different.
