How many cups is 400g?

To determine how many cups 400g is, you need to know the density of the substance in question. Density is defined as mass per unit volume. If we assume that the substance has a density of 1 gram per cubic centimeter (g/cm³), then we can calculate the volume of 400 grams as follows:

Volume = Mass / Density

Volume = 400 g / 1 g/cm³

Volume = 400 cm³

Now, to convert cubic centimeters to cups, we need to divide the volume by the volume of 1 cup in cubic centimeters. There are approximately 236.6 cubic centimeters in 1 cup. Therefore, we can calculate the number of cups in 400 grams as follows:

Number of cups = Volume / Volume of 1 cup

Number of cups = 400 cm³ / 236.6 cm³/cup

Number of cups ≈ 1.69 cups

Therefore, 400g is approximately equal to 1.69 cups. Please note that this calculation assumes a density of 1 g/cm³, which may not be accurate for all substances. If you know the exact density of the substance in question, you can use that value to calculate the volume and number of cups more precisely.
