Grams to Cups Converter
100 grams of plain flour is about 0.8 cups, 100 grams of sugar is about 0.5 cups, and 100 grams of butter is about 0.44 cups. The cup figure changes with the ingredient because each one has its own density, so pick the ingredient below, enter the weight in grams, and read off the cup amount. The converter handles any common baking ingredient.
This converter uses the metric cup (250 ml) by default. A US cup is 240 ml, about 4 percent smaller, so the same weight comes out to slightly more US cups. To get your answer in US cups, choose Cup (US) in the Convert to menu. For the difference between US, metric, and UK cups, see what is a cup measurement.

Why You Can't Use a Single Conversion Factor
There's no universal grams-to-cups conversion — every ingredient has its own density. A cup of flour weighs about 140 grams, but a cup of sugar weighs around 200 grams, and a cup of butter weighs 227 grams. Always pick the ingredient before converting, or you'll be off by a significant amount.
For ingredient-specific guidance, see the dedicated pages for plain flour, sugar, butter, or brown sugar.

Frequently Asked Questions
- How many cups is 100 grams of flour?
- 100 grams of plain flour is about 0.71 cups, a little over two thirds of a metric cup. One metric cup of plain flour weighs 140 grams, so 100 divided by 140 gives 0.71. Spoon the flour into the cup and level it off rather than scooping, since packing it down can add 20 grams or more. Open flour converter
- How many cups is 200 grams of sugar?
- 200 grams of granulated sugar is exactly 1 metric cup. One metric cup of white sugar weighs about 200 grams, so 200 grams fills a full cup. Sugar is denser than flour, which is why the same 200 grams gives far fewer cups of sugar than it would of flour. Open sugar converter
- How do I convert grams to cups?
- Divide the weight in grams by the weight of one cup of that ingredient. One metric cup of plain flour is 140 grams, so 250 grams of flour is 250 divided by 140, which is about 1.79 cups. Every ingredient has its own cup weight, so always pick the ingredient first. A grams to cups converter does this automatically.
- Why does the same gram amount give different cups for different ingredients?
- Cups measure volume while grams measure weight. Denser ingredients such as sugar or butter pack more weight into the same space than light ingredients such as flour or rolled oats. One metric cup holds 200 grams of sugar but only 140 grams of flour, so 100 grams of sugar takes up far less room in the cup than 100 grams of flour.
- How many grams are in a cup?
- It depends on the ingredient, since each one has its own density. One metric cup (250 ml) of plain flour weighs about 140 grams, white sugar about 200 grams, brown sugar about 220 grams, and butter about 227 grams. Light, airy ingredients weigh the least per cup, while dense or sticky ones weigh the most. Pick the ingredient in the converter for an exact figure. See all ingredients
- How many cups is 150 grams of flour?
- 150 grams of plain flour is about 1.07 cups, just over one metric cup. One metric cup of plain flour weighs 140 grams, so 150 divided by 140 gives 1.07. For self raising flour the answer is the same, since it shares the same density as plain flour at 140 grams per metric cup. Open self raising flour converter
