About the Cups to Grams Calculator
Weighing ingredients makes baking far more consistent than scooping with cups, and many modern recipes list grams. Use this converter when your recipe is in cups but you want to weigh, or when you are translating a US recipe for someone who cooks in metric.
One US cup is 236.6 mL. A metric cup (used in Australia, New Zealand and Canada) is 250 mL, about 6% larger, so add a little if your recipe uses metric cups.

grams = cups × grams per cup of the ingredient
