How to Use the Grams to Cups Converter
The conversion from grams to cups sounds straightforward enough, but there is one little thing that you must know: grams to cups is a conversion of weight to volume that naturally involves the densityof the substance.
- Select the ingredient for which you would want to convert. Click on the drop-down button, and you will see a list of 20+ different kitchen ingredients. If your ingredient is not listed, choose "Custom" and enter the density manually.
- Next, you may enter the weight of the chosen ingredient. The default unit isgrams, but you can choose a different one from the list of options (including micrograms, milligrams, kilograms, ounces, pounds, and even scientific units). Make sure to select the unit before entering the value.
- Select the cup type (US customary cups for recipes, US legal cups for nutrition, or UK/AU/CA/ZA metric cups).
- The amount in cups is converted instantly.
For example, you need to know the amount of flour in cups for the cake you are making, and the recipe says 250 g. The calculator will convert it and tell you it is equal to approximately 1.76 US cups.
You may also use the calculator in reverse. After selecting the ingredient, enter theamount in cups, and our efficient tool will display the equivalent in grams (or your selected weight unit).
In our grams to cups converter, we present twenty popular ingredients. If you cannot find your ingredient on our list and want to be super accurate, you can visit this density database. Find your product, type its density into the right field (in kg/m³), and the grams to cups calculator will convert it for you. If you need to convert the units of volume only, use our volume converter.
How to Convert Grams to Cups and Cups to Grams?
General equations look as follows:
cups = weight / (cup size × density)
To convert weight to cups, divide the weight (in grams) by the product of cup size (in mL) and density (in g/mL).
weight = cups × cup size × density
To convert cups to weight, multiply the cups by the cup size (in mL) and density (in g/mL).
As you can see in the formulas above, providing only the amount of grams is not enough to convert grams to cups. We need to know the density of the ingredient we want to convert. To make it more complicated, there are different types of cups, so we need to know our recipe's country of origin.
Various Cups Sizes
The most often used cup volume is the US customary cup with 236.59 mL of volume. If you have a recipe from the USA, you may be pretty sure that it's what the authors meant. There is also another cup type in the USA, and it's called a legal cup. It is used in nutrition labeling, and it measures 240 mL.
Other countries occasionally use cup units, and the recipes normally weigh non-liquid ingredients in grams rather than measuring volume. UK imperial cup was used in pre-1970 recipes. Sometimes the metric cup (250 mL) is still used in the UK, Australia, New Zealand, Canada, and South Africa.
| Cup type | Volume |
|---|---|
| US customary cups | 236.59 mL |
| US legal cup | 240 mL |
| UK, AU, NZ, CA, ZA metric cup | 250 mL |
| UK imperial cup (pre-1970) | 284.13 mL |
| Japanese cup | 200 mL (traditional – 180.4 mL) |
| Latin America | 200-250 mL |
You can choose between the first three cup types in our grams to cups converter.
How Many Grams in a Cup of My Product?
The weight of 1 cup differs for various ingredients, depending on their density. For example, if you want to convert one standard US cup of water into grams, you get exactly 236.59 g. However, 1 cup of salt weighs around 287 g, and 1 cup of wheat flour – only 141.6 g. Below we attach the density conversion table for the most often-used products:
| Product | Density (kg/m³) | Grams in 1 cup (US) | 100 grams to cups (US) |
|---|---|---|---|
| Water | 1000 | 236.59 | 0.42 |
| Flour | 600 | 141.60 | 0.71 |
| Milk | 1030 | 243.08 | 0.41 |

⚠️ Important Note: Those values are only approximate and may be slightly different for your ingredient, as the density of the substance varies with pressure and temperature. Also, it is essential to know how tightly the ingredient is packed into the cup. For the most accurate results, use a kitchen scale to weigh your ingredients.
