## How to Convert Pounds Per Cubic Feet to Slugs Per Cubic Feet

*Example: How many slugs per cubic feet are equivalent to 18.39 pounds per cubic feet?*

As;

1 pounds per cubic feet = 0.03108 slugs per cubic feet

18.39 pounds per cubic feet = Y slugs per cubic feet

Assuming Y is the answer, and by criss-cross principle;

Y equals 18.39 times 0.03108 over 1

(i.e.) Y = 18.39 * 0.03108 / 1 = 0.5715612 slugs per cubic feet

Answer is: 0.5715612 slugs per cubic feet are equivalent to 18.39 pounds per cubic feet.
