Grams to Cups Converter
Converting grams to cups is the one baking conversion where the ingredient itself matters: a cup of flour weighs 125 g, but a cup of sugar weighs 200 g and a cup of honey nearly 340 g. Pick the ingredient from the list and both directions convert with the right density.
Results include a friendly fraction estimate (like ⅔ cup) because nobody measures 0.67 cups. For best baking results, grams win — a scale removes the packing-error that makes cup measurements unreliable — but when only cups exist, this converter keeps the recipe honest.
How to use
- Choose the ingredient from the dropdown — density differs for every one.
- Type grams to see cups, or type cups to see grams; both directions update live.
- Use the fraction shown as the practical measuring-cup answer.
Frequently asked questions
How many grams is a cup of flour?
About 125 g for all-purpose flour spooned and leveled. Scooping directly from the bag compresses it and can reach 150 g+ — which is why weight recipes beat cup recipes.
How many grams is a cup of sugar?
Granulated sugar: about 200 g per cup. Brown sugar (packed): about 213 g. Powdered sugar is much lighter: about 120 g per cup.
Why do grams and cups disagree between websites?
Because cups measure volume, not weight — the answer depends on how densely the ingredient is packed. Reputable sources agree closely on standard weights (flour 120–130 g per cup), and this converter uses the widely accepted values.
Should I switch my recipes to grams?
If you bake regularly, yes: a scale costs little and removes the single biggest source of baking failure. Use this converter to translate your existing cup recipes once, then weigh forever after.
