How many cups is 40 grams of oats?

To calculate the number of cups in 40 grams of oats, we need to know the density of oats. The density of oats is approximately 0.6 grams per cubic centimeter (g/cm³).

Volume = Mass/Density

Volume = 40 g / 0.6 g/cm³

Volume ≈ 66.67 cm³

Since 1 cup is approximately equal to 240 cubic centimeters (cm³):

Number of cups = Volume of oats (cm³) / Volume of 1 cup (cm³)

Number of cups ≈ 66.67 cm³ / 240 cm³

Number of cups ≈ 0.278 cups

Therefore, 40 grams of oats is approximately equal to 0.278 cups.
