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

*Example: How many pounds per cubic inches are equivalent to 40.35 slugs per cubic feet?*

As;

1 slugs per cubic feet = 0.018616898148148 pounds per cubic inches

40.35 slugs per cubic feet = Y pounds per cubic inches

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

Y equals 40.35 times 0.018616898148148 over 1

(i.e.) Y = 40.35 * 0.018616898148148 / 1 = 0.75119184027778 pounds per cubic inches

Answer is: 0.75119184027778 pounds per cubic inches are equivalent to 40.35 slugs per cubic feet.
