100 grams to cups

100 grams is about 5/6 cups of flour, 1/2 cups of sugar, or 7/16 cups of butter. Because grams measure weight and cups measure volume, the answer changes with the ingredient — here is 100 g in cups for everything in the pantry.

How to convert 100 grams to cups

To turn 100 grams into cups, divide the weight by the weight of one cup of your ingredient. For all-purpose flour, one cup weighs about 120 grams, so:

100 g ÷ 120 g per cup = 0.83 cups of flour (≈ 5/6 cups)

Swap in a different per-cup weight for other ingredients. A kitchen scale is always more accurate than cups for baking, but when a recipe only gives you cups, the table above gets you very close.

Frequently asked questions

How many cups is 100 grams?

It depends on the ingredient because each one has a different density. 100 grams of all-purpose flour is about 5/6 cups, 100 grams of granulated sugar is about 1/2 cups, and 100 grams of butter is about 7/16 cups.

Why isn't 100 grams a fixed number of cups?

Grams measure weight while cups measure volume. A cup of flour weighs around 120 g, but a cup of sugar weighs about 200 g, so the same 100 g fills a different number of cups depending on what you are measuring.

Is 100 grams to cups the same for dry and liquid ingredients?

No. Liquids such as water, milk, and honey are denser than most dry goods, so 100 g of honey fills far fewer cups than 100 g of flour. Use the table above to pick the right ingredient.
