How to Convert Pounds Per Linear Inches to Pounds Per Linear Feet
Example: How many pounds per linear feet are equivalent to 21.81 pounds per linear inches?
As;
1 pounds per linear inches = 12 pounds per linear feet
21.81 pounds per linear inches = Y pounds per linear feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 21.81 times 12 over 1
(i.e.) Y = 21.81 * 12 / 1 = 261.72 pounds per linear feet
Answer is: 261.72 pounds per linear feet are equivalent to 21.81 pounds per linear inches.
