Grams to Cups Converter
To convert grams to cups, divide the weight by what one cup of the ingredient weighs, then measure it with the cups and spoons in your drawer. 100 g of all-purpose flour is 0.8 cup, which is about 2/3 cup + 2 tbsp + 1/2 tsp. 100 g of granulated sugar is 0.5 cup (exactly 1/2 cup) and 100 g of butter is 0.441 cup (about 1/4 cup + 3 tbsp).
0.8 cup
100 grams of all-purpose flour = 0.8 cup (US legal cup, 240 ml)
Measure it: 2/3 cup + 2 tbsp + 1/2 tsp (within 1%)
100 grams of all-purpose flour = 0.8 cup (US legal cup, 240 ml)
All-Purpose Flour: 125 g per US cup. See full table →

Measures use a US cup (240 ml), a 15 ml tablespoon and a 5 ml teaspoon, and none is more than 2% off the weight. Any other weight or ingredient: type it into the converter above, or see every ingredient in the baking conversion chart.
How to measure grams with cups and spoons
- Find what one cup weighs. Every ingredient page lists it: a cup of all-purpose flour is about 125 g, granulated sugar 200 g and butter 227 g.
- Divide the grams by that weight. 83 g of flour divided by 125 g is 0.664 cup.
- Fill the whole cups, then the largest measuring cup that fits. 0.664 cup is about 2/3 cup, close enough that no spoon is needed.
- Top up with spoons when the cup is not close. A US cup holds 16 tablespoons and a tablespoon 3 teaspoons, so 0.8 cup becomes 2/3 cup + 2 tbsp + 1/2 tsp.
Going from weight back to volume
Grams to cups is the reverse trip of the classic cups to grams question, and it comes up constantly when an American kitchen meets a European recipe. Most of the world writes recipes by weight, so a cake might call for 300 grams of flour and 150 grams of sugar. If your kitchen runs on measuring cups rather than a scale, you need to translate that weight into volume, and the translation is different for every ingredient.
The math is a single division: grams divided by the ingredient's density in grams per US cup. 300 grams of all-purpose flour at 125 grams per cup comes to 2.4 cups. The same 300 grams of granulated sugar, at about 200 grams per cup, is only 1.5 cups. Guessing one conversion for both would put your flour badly out of proportion, which is exactly the mistake this converter exists to prevent.
One honest caveat: converting weight to volume always loses a little precision, because how you scoop matters. Flour that is spooned lightly into a cup weighs less than flour that is scooped and packed. When a bake is sensitive, treat the cup figure as a good starting point, and consider weighing with a kitchen scale when you can. For everything else, the numbers here will keep your ratios comfortably in range.

Frequently asked questions
How many cups is 100 grams?
It depends on the ingredient. 100 grams of all-purpose flour is 0.8 cup, 100 grams of granulated sugar is 0.5 cup and 100 grams of honey is 0.294 cup. Grams measure weight and cups measure volume, so the density of each ingredient decides the answer.
How do I convert grams to cups?
Divide the weight in grams by what one cup of the ingredient weighs. 250 grams of all-purpose flour divided by 125 grams per cup is 2 cups. Then measure the result with the closest measuring cup and top up with spoons if needed: 83 grams of flour is 0.664 cup, which is about 2/3 cup.
How many cups is 250 grams of flour?
250 grams of all-purpose flour is 2 cups, because a US cup of flour weighs about 125 grams. The same 250 grams of granulated sugar is 1.25 cups (exactly 1 1/4 cups), because sugar is denser and packs more weight into each cup.
How do I measure an amount like 0.8 cup?
Fill the largest measuring cup that fits, then top up with tablespoons and teaspoons. A US cup holds 16 tablespoons and a tablespoon holds 3 teaspoons, so 0.8 cup is about 2/3 cup + 2 tbsp + 1/2 tsp. When the amount lands within 2% of a single measuring cup, that cup alone is close enough: 0.664 cup is about 2/3 cup.
Why does my recipe give grams instead of cups?
Most of the world writes recipes by weight because it is more precise and consistent than volume. If you only own measuring cups, a grams to cups converter translates those weights into something you can scoop, though a kitchen scale is still the more accurate route.
