How it works
When a recipe gives weights but you only have measuring cups, this calculator converts grams to cups. You enter the weight in grams and the ingredient's density in grams per cup, and it returns the volume in cups and tablespoons. The conversion divides grams by grams per cup, so the result depends entirely on the ingredient's density: 240 grams of flour (at 120 grams per cup) is 2 cups, but 240 grams of sugar (at about 200 grams per cup) is only 1.2 cups. Common densities include all-purpose flour around 120 grams per cup, granulated sugar around 200, packed brown sugar around 220, butter around 227, and water around 237. Because volume measuring is inherently less precise than weighing, converting from a precise weight to cups introduces some approximation — how you scoop and level affects the true volume — so treat the cups result as a close guide rather than an exact figure. This conversion is handy when following international recipes that use metric weights, or when you have a weight from a nutrition label or bulk purchase and need a familiar volume. For the best accuracy in baking, weighing is still preferable, but cups are convenient for quick cooking. Enter the grams and grams per cup to convert to cups.
Cups = grams ÷ grams per cup
To convert a weight in grams to a volume in cups, divide the grams by the ingredient's density in grams per cup. Because each ingredient has its own density, the grams-per-cup value must match the ingredient. Multiplying cups by 16 gives the equivalent in tablespoons.

Frequently asked questions
How do you convert grams to cups?
Divide the weight in grams by the ingredient's density in grams per cup. For example, 240 grams of flour at 120 grams per cup equals 2 cups. Because ingredients differ in density, you must use the correct grams-per-cup value for your specific ingredient to get an accurate volume conversion.
Why does the ingredient matter?
Grams measure weight and cups measure volume, and each ingredient packs differently. The same 240 grams is 2 cups of flour but only about 1.2 cups of sugar, because sugar is denser. So there is no universal grams-to-cups number; the conversion always depends on the specific ingredient's grams-per-cup density.
How many tablespoons are in a cup?
There are 16 tablespoons in a US cup, so the calculator multiplies your cups result by 16 to give tablespoons. This is useful for small amounts, where measuring a fraction of a cup as tablespoons is easier and more accurate. For instance, a quarter cup is 4 tablespoons and an eighth of a cup is 2 tablespoons.
Is converting grams to cups exact?
Not perfectly. Weighing is precise, but cups depend on how you scoop, pack, and level the ingredient, so the converted volume is a close approximation rather than an exact figure. For most cooking this is fine, but for delicate baking, following the recipe's weight with a scale gives more reliable results than converting to cups.
When is this conversion useful?
It helps when a recipe lists metric weights but you only have measuring cups, common with international or professional recipes. It is also handy when you have a weight from a package label or bulk amount and want a familiar cup measure. Just remember to use the right density for your ingredient to get a meaningful result.
