400 Grams of sugar are how many cups?

To convert grams of sugar to cups, you need to know the density of sugar. The density of granulated sugar is approximately 0.65 grams per cubic centimeter (g/cm³).

First, convert the mass of sugar from grams to kilograms:

400 grams = 400 / 1000 = 0.4 kilograms

Then, calculate the volume of sugar using the density formula:

Volume = Mass / Density

Volume = 0.4 kg / 0.65 g/cm³

Volume ≈ 0.6153846... cubic centimeters

Finally, convert the volume from cubic centimeters to cups:

1 cup = 236.5882365 cubic centimeters

Volume in cups = Volume in cubic centimeters / Volume of 1 cup

Volume in cups ≈ 0.6153846... cm³ / 236.5882365 cm³/cup

Volume in cups ≈ 0.002603... cups

Therefore, 400 grams of sugar is approximately 0.002603 cups.
