## How to Convert Atmospheres to Kilopounds Per Square Inches

*Example: How many kilopounds per square inches are equivalent to 42.24 Atmospheres?*

As;

1 Atmospheres = 0.01469181 kilopounds per square inches

42.24 Atmospheres = Y kilopounds per square inches

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

Y equals 42.24 times 0.01469181 over 1

(i.e.) Y = 42.24 * 0.01469181 / 1 = 0.6205820544 kilopounds per square inches

Answer is: 0.6205820544 kilopounds per square inches are equivalent to 42.24 Atmospheres.
