About this site
gramsinacup.com exists because we got tired of Googling "how many grams in a cup of flour" every time we opened a recipe from a different country.
American recipes use cups. European recipes use grams. And the conversion is never as simple as a single number — it depends on the ingredient, how you measure, and sometimes even the brand. A cup of all-purpose flour can weigh anywhere from 100 to 150 grams depending on whether you spooned it gently or scooped it from the bag.
Most converter tools give you the number and nothing else. We think the context matters just as much: why does brown sugar need to be packed? Why is cocoa powder so much lighter than flour? Why does your grandmother's cookie recipe never turn out the same when you make it?
Every ingredient page on this site includes the conversion, a measurement table, an interactive calculator, and practical baking tips — the kind of advice that usually requires years of experience or a pastry school diploma.
Who runs this site
Stefan Ulrich — Founder & editor. Stefan founded gramsinacup.com after years of converting American cup-based recipes into grams. He compiles and tests the gram-per-cup values against USDA FoodData Central and King Arthur Baking references.
Where our data comes from
Our gram-per-cup values are based on the USDA FoodData Central database, cross-referenced with King Arthur Baking, the Culinary Institute of America references, and practical testing. Where sources disagree, we list the most widely accepted standard and note the variation range.
