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

*Example: How many pounds per square inches are equivalent to 5.43 kilopounds per square inches?*

As;

1 kilopounds per square inches = 1000 pounds per square inches

5.43 kilopounds per square inches = Y pounds per square inches

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

Y equals 5.43 times 1000 over 1

(i.e.) Y = 5.43 * 1000 / 1 = 5430 pounds per square inches

Answer is: 5430 pounds per square inches are equivalent to 5.43 kilopounds per square inches.
