Grams to Cups Converter
The reverse journey: you have grams — a European recipe, a package, the end of a bag — and a drawer of American cups. Decimals and the kitchen fractions you can actually measure.
Why the reverse direction deserves its own page
Most converters treat grams-to-cups as the main tool run backwards. It isn't — the questions are different. Going forward, you have a recipe in cups and a scale; going backward, you have a European recipe, a package weight, or the last 250 g in the flour bag, and a set of American measuring cups. The answer you need is not a decimal like 2.0833 cups — nobody owns a 0.0833 cup — but the nearest honest way to fill real cups: two level cups and a tablespoon, in that example. That is why this converter leads with the kitchen fraction, and why the table below pairs every decimal with its fraction.
It is also the direction where rounding does real damage if you let it. Rounding 2.08 cups of flour down to 2 cups drops about 10 g — invisible. Rounding 0.51 cups of sugar to a half is harmless too. But rounding compounds across a whole recipe converted ingredient by ingredient, each one shaved a little low, until a cake's ratios quietly wander. Use the fractions, or better, weigh the big ingredients and save the cups for the small ones.

Frequently asked questions
How many cups is 250 grams of flour?
250 g of all-purpose flour is 2.08 US cups — about 2 cups plus 1 tablespoon — using the King Arthur chart's 120 g per cup (250 ÷ 120). The popular-weights table on this page works out the standard amounts for eight staple ingredients.
How many cups is 100 grams of sugar?
100 g of granulated sugar is 0.51 US cups — essentially half a cup — at the chart's 198 g per cup. Brown sugar differs (213 g per packed cup), so check the right row of the table.
Why aren't grams-to-cups results ever tidy numbers?
Because grams and cups were never designed to meet. A cup is a volume from the imperial tradition; the gram is a unit of mass. Dividing one by the other gives repeating decimals, which is why this page shows both the decimal and the nearest standard kitchen fraction — and why weighing will always beat converting.
Why does this page give slightly different cups than other sites?
Two reasons: the source chart (this site uses King Arthur's weights, e.g. 120 g per cup of flour, where USDA-based sites use 125 g) and the cup definition (US customary 236.588 mL here, not the 250 mL metric cup). Both choices are stated on the page so you can match your recipe's origin.
