Grams to Cups Converter
Got a weight in grams and no kitchen scale? Pick your ingredient and turn grams into cups instantly — accurately, because a cup of flour and a cup of sugar are not the same weight.
Why 100 g isn't always the same number of cups
Grams measure weight; cups measure volume. The same weight fills a different number of cups for each ingredient because their densities differ. Here is what 100 g looks like across some common ingredients:
| Ingredient | 100 g in cups |
|---|---|
| All-Purpose Flour | 0.83 cups |
| Granulated Sugar | 0.5 cups |
| Butter | 0.44 cups |
| Brown Sugar (packed) | 0.47 cups |
| Powdered Sugar | 0.88 cups |
| Milk | 0.42 cups |

Frequently asked questions
How do I convert grams to cups?
Divide the weight in grams by the weight of one cup of that ingredient. For example, 1 cup of all-purpose flour is about 120 g, so 240 g of flour is 240 ÷ 120 = 2 cups. Pick your ingredient above and the calculator does the math for you.
Is grams to cups the same for every ingredient?
No — this is the key thing. A cup of flour weighs about 120 g, but a cup of granulated sugar is about 200 g and a cup of honey about 340 g. So 100 g is a very different number of cups depending on the ingredient. Always convert by ingredient, never with a single ratio.
How many cups is 100 grams?
It depends on the ingredient: 100 g of all-purpose flour is about 0.83 cups, 100 g of granulated sugar about 0.5 cups, and 100 g of butter about 0.44 cups. Choose your ingredient above for an exact figure.
How many cups is 250 grams of flour?
About 2.08 cups of all-purpose flour, based on 120 g per cup. For sugar (200 g per cup) 250 g is about 1.25 cups.
Why does my recipe give weights in grams?
Weighing is more accurate than measuring by volume — packed versus sifted flour can differ by 30%. Recipes written in grams remove that guesswork. This converter lets you turn those gram weights back into cups when you don't have a scale.
