- Based on a “scoop and level” all-purpose flour (spooned & levelled) cup. Packed or sifted ingredients weigh differently.
- Using the metric cup (250 ml). Switch to US for the 240 ml cup.
- For baking, weighing in grams is far more accurate than measuring by volume.
What is the Cups to Grams Converter?
A cup of flour and a cup of sugar weigh very different amounts, which is why a single “cups to grams” number is misleading. This converter uses the real density of each of 100+ ingredients — sourced from King Arthur Baking and USDA data — to give an accurate weight. It even accounts for how you measure: flour scooped, spooned or sifted weighs differently, as does packed vs loose brown sugar and each salt brand. Pick your ingredient, enter an amount in cups, tablespoons, millilitres or grams, and switch between the US cup (240 ml) and metric cup (250 ml).
How to use the Cups to Grams Converter
- 1 Choose the ingredient you’re measuring.
- 2 Enter the amount and the unit you have.
- 3 Read the accurate weight in grams and ounces.
Cups to grams chart for common ingredients
There is no single cups-to-grams number — weight depends entirely on what you are measuring. These are the same densities the converter above uses, at the quantities recipes ask for most.

- Based on the US cup (240 ml). A metric 250 ml cup holds about 4% more — switch the toggle on the converter to see those weights.
- Flour is listed three ways because the measuring method matters more than the flour: scooping straight from the bag compacts it to 142 g, while sifting drops it to 110 g.
- Densities come from King Arthur Baking’s ingredient weight chart, cross-checked against USDA FoodData Central, rounded to the nearest gram.
Frequently asked questions
How many grams is one cup of flour? +
About 120 g for all-purpose flour spooned into the cup and levelled. If you scoop straight from the bag it compacts to ~142 g; sifted it drops to ~110 g. Pick the matching entry for an accurate weight.
Why isn’t there one cups-to-grams number? +
Because weight depends on density. A cup of feathery powdered sugar weighs far less than a cup of honey, so the only accurate way is per-ingredient — and even per measuring method — which is exactly what this tool does.
How accurate are the results? +
The figures come from standard, tested references (USDA FoodData Central and King Arthur Baking) and are excellent starting points. Ovens, ingredients and equipment vary, so treat the numbers as a reliable guide and adjust to taste and doneness.
Is this calculator free, and does it send my data anywhere? +
Yes — it’s completely free and runs entirely in your browser. Nothing you type is uploaded or stored on a server; the maths happens on your device, even offline once the page has loaded.
