Important limitations
Uses USDA FoodData Central weights for a US cup (236.6 mL). Metric and UK cups are larger, and packed or scooped ingredients can weigh noticeably more.
Frequently asked questions
Why does 100 g of flour and 100 g of sugar give different cups?
Cups measure volume and grams measure weight. Sugar is denser than flour, so the same 100 g fills less of a cup: 0.5 cup of sugar at 200 g per cup, but 0.8 cup of all-purpose flour at 125 g per cup.
Where do the weights per cup come from?
They are USDA FoodData Central household measures for a US cup (236.6 mL), for example 125 g for all-purpose flour and 227 g for butter. Recipes from other sources can assume slightly different values.
My recipe uses metric cups. Is that different?
Yes. An Australian or metric cup is 250 mL, about 6 percent larger than the US cup used here. For a metric-cup recipe, multiply the cups shown by about 0.95.
Why is flour so hard to measure by cups?
Scooping packs flour down and can add 20-30 percent more than spooning it in and leveling. That is why bakers weigh flour; use the gram value when you can.
How are the fractions rounded?
Cups are rounded to the nearest common kitchen measure (1/8, 1/4, 1/3, 3/8, 1/2, 5/8, 2/3, 3/4 or 7/8), and the exact decimal and the tablespoon equivalent are shown too.
