## How to Convert Pounds Per Square Feet to Kilopounds Per Square Feet

*Example: How many kilopounds per square feet are equivalent to 77.71 pounds per square feet?*

As;

1 pounds per square feet = 0.001 kilopounds per square feet

77.71 pounds per square feet = Y kilopounds per square feet

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

Y equals 77.71 times 0.001 over 1

(i.e.) Y = 77.71 * 0.001 / 1 = 0.07771 kilopounds per square feet

Answer is: 0.07771 kilopounds per square feet are equivalent to 77.71 pounds per square feet.
