## How to Convert Pounds Per Linear Inches to Pounds Per Linear Feet

*Example: How many pounds per linear feet are equivalent to 25.75 pounds per linear inches?*

As;

1 pounds per linear inches = 12 pounds per linear feet

25.75 pounds per linear inches = Y pounds per linear feet

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

Y equals 25.75 times 12 over 1

(i.e.) Y = 25.75 * 12 / 1 = 309 pounds per linear feet

Answer is: 309 pounds per linear feet are equivalent to 25.75 pounds per linear inches.
