What is a Gram?

A gram is a metric unit of mass equal to one-thousandth of a kilogram. Measuring ingredients by weight avoids variations caused by scooping, packing, humidity, and settling.

For baking, grams make recipes repeatable and easier to scale. A measured 100 grams remains 100 grams in every kitchen.

What is a Cup?

A US customary cup is a volume measurement of about 236.6 milliliters. Because a cup measures space rather than weight, every ingredient has a different gram equivalent.

A cup of flour can weigh around 120 grams, while the same cup filled with granulated sugar weighs about 200 grams. That is why ingredient-specific conversions are essential.

Grams to Cups Formula

Cups = Grams ÷ Grams per Cup

The calculator selects the grams-per-cup value for your chosen ingredient, divides the weight by that value, and returns a practical kitchen fraction and decimal estimate.

240g flour: 2 cups
227g butter: 1 cup
400g sugar: 2 cups

How to Convert Grams to Cups

Identify the ingredient. Flour, sugar, butter, and liquids have different densities.
Select it in the converter. The correct grams-per-cup reference is applied.
Enter the gram amount. The converter calculates the US cup volume.
Use the result carefully. A digital scale remains best for precision.

Frequently Asked Questions

How many cups is 250 grams of flour?

About 2.08 US cups using 120 grams per cup. For repeatable results, spoon flour into the measuring cup and level the top.

Can I convert any ingredient from grams to cups?

Yes, when its grams-per-cup weight is known. Ingredient density matters, so flour, sugar, butter, and liquids need different conversion values.

Why do European recipes use grams?

Weight measurements are consistent and easy to scale. One hundred grams is the same amount regardless of how an ingredient is scooped or packed.

Is 240 grams always equal to one cup?

No. A cup measures volume and grams measure weight. For example, 240 grams of flour is about 2 cups, while 240 grams of water is about 1 cup.

Should brown sugar be packed?

Most recipes mean firmly packed brown sugar unless stated otherwise. Packed brown sugar weighs substantially more per cup than loosely filled sugar.

Does the recipe parser upload my recipe?

No. Conversion and recipe parsing happen locally in your browser, and the current tool does not send recipe text to a server.
