Grams to Cups Calculator

How it works

cups = grams ÷ grams per cup (ingredient density) · tablespoons = cups × 16 · other cup sizes: cups × 236.6 mL ÷ cup size in mL · grams per cup = density in g/mL × 236.6

Grams measure weight and cups measure volume, so the conversion depends on how dense the ingredient is. A cup of all-purpose flour weighs about 120 g, but a cup of honey weighs 340 g, nearly three times as much, which is why no single grams-to-cups number works. The calculator divides your weight by the grams-per-cup figure for the ingredient you pick, then shows the answer as decimal cups, as a measuring breakdown such as “2 cups + 1 tbsp + 1 tsp”, and in tablespoons and millilitres. Flours, sugars, nuts and mix-ins follow the King Arthur Baking ingredient weight chart (spooned and leveled); liquids, fats and dairy use USDA FoodData Central weights. You can enter the weight in grams, kilograms, ounces or pounds; choose “Other” to type your own grams per cup or g/mL; and, under More options, switch to a 250 mL metric cup, a 240 mL label cup, the UK imperial cup or the 200 mL Japanese cup, or see how scooping or sifting flour changes the result.

Worked example

You have 250 g of all-purpose flour, and flour weighs about 120 g per cup when spooned and leveled. 250 ÷ 120 = 2.08 cups, which you measure as 2 cups + 1 tbsp + 1 tsp (33.3 tablespoons in all). If the recipe uses 250 mL metric cups, the same flour is 2.08 × 236.6 ÷ 250 = 1.97 metric cups. For 250 g of granulated sugar the answer is 250 ÷ 200 = 1.25 cups — 1 ¼ cups.
