Baking pan sizes and volumes chartWhy grams beat cups
A cup is a measure of space, not weight. Fill that cup with spooned flour and it holds about 120 grams; fill it with granulated sugar and it holds about 198 grams; fill it with honey and it holds 340 grams. Any converter that uses one number for all three is wrong for at least two of them — and that is before technique gets involved. Scooping flour straight from the bag can pack in 20 percent more than spooning it into the cup and levelling it off, which is enough to turn a light cake dense and dry.
That is why professional bakers weigh. A scale does not care how you filled the cup, because there is no cup. GramChef exists to make weighing easy when a recipe was written in cups: every ingredient in our database carries its own published weight, our methodology page shows exactly where each number comes from, and the values are reviewed by a certified chef who works with these conversions in a professional kitchen. If you do not own a scale yet, our converters still give you the most careful cup equivalents available.
Frequently asked questions
Why do recipes fail when I convert cups to grams with one fixed number?
A single fixed number cannot work because a cup measures volume, not weight, and every ingredient has a different density. One cup of all-purpose flour weighs about 120 g, while one cup of granulated sugar weighs about 198 g and one cup of butter weighs 227 g. Converting all three with the same number guarantees at least two of them are wrong, which is why GramChef stores a separate, published weight for every ingredient.
Is GramChef really free?
Yes. Every tool on GramChef is free to use, with no account, no sign-up and no usage limit. All calculations run in your own browser, so the recipes you paste are never uploaded or stored anywhere. The site is kept free by advertising, which is disclosed in our privacy policy.
Where do GramChef's conversion numbers come from?
Our primary source is the King Arthur Baking ingredient weight chart, the most widely used published reference for cups-to-grams baking weights. Ingredients it does not cover use typical values from USDA FoodData Central. Every value assumes the spoon-and-level method for dry ingredients and a standard US cup of 236.588 ml, as explained on our methodology page.
Can I convert a whole recipe at once instead of line by line?
Yes — that is exactly what our Whole Recipe Converter is for. Paste your full ingredient list, one ingredient per line, choose grams or cups as the target, and the tool converts every line it recognises in one pass. Lines it cannot match to our ingredient database are shown unchanged and clearly flagged, so nothing is silently guessed.
Should I weigh ingredients or use cups?
Weighing is more accurate and more repeatable, especially for flour, where the difference between a scooped cup and a spooned-and-levelled cup can reach 20 percent or more. Cups are fine for liquids and forgiving recipes, but a small kitchen scale removes the biggest source of error in home baking. Our tools help either way: convert to grams when you have a scale, and get careful cup equivalents when you do not.
