Grams to Cups Converter
Convert grams to cups accurately based on the ingredient you are measuring.
100g ÷ 125g per cup = 0.8 cups
Why ingredient matters: grams measure weight while cups measure volume. Different ingredients have different densities, so 100 grams of flour does not equal the same number of cups as 100 grams of sugar or butter.

Grams measure weight, while cups measure volume. That means the same number of grams can equal different cup amounts depending on the ingredient. For example, flour is lighter than sugar, while butter is denser, so each needs its own conversion value.

Frequently Asked Questions
Quick answers to common grams and cups conversion questions.
How many cups is 100 grams?
It depends on the ingredient. For example, 100 grams of all-purpose flour is about 0.80 US cup, while 100 grams of granulated sugar is about 0.50 cup.
How many grams are in 1 cup?
There is no single grams-per-cup value for every ingredient. One US cup of all-purpose flour is about 125 grams, while one cup of granulated sugar is about 200 grams.
Is 1 cup always the same weight?
No. Cups measure volume while grams measure weight. Flour, sugar, butter, rice, oats, and other ingredients can therefore weigh different amounts in the same cup.
Are US cups and metric cups the same?
No. A US customary cup is approximately 236.6 ml, while a metric cup is 250 ml. Select the correct cup standard in the converter for your recipe.
Why does the ingredient matter when converting grams to cups?
Ingredients have different densities. That means 100 grams of flour occupies a different volume than 100 grams of sugar, butter, honey, or rice.
Are grams more accurate than cups?
Grams are often more precise because they measure weight directly. Cup measurements can vary depending on how ingredients are scooped, packed, or filled.
