**Definitions:**

**Pound Per Square Inch** (abbreviations: **psi, or lb/in2**): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

**Kilopascal** (abbreviations: **kPa, or kN/m2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one kilonewton per square meter. It is named after the French polymath Blaise Pascal.

## How to Convert Pounds Per Square Inches to Kilopascals

*Example: How many kilopascals are equivalent to 54.23 pounds per square inches?*

As;

1 pounds per square inches = 6.89476 kilopascals

54.23 pounds per square inches = Y kilopascals

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

Y equals 54.23 times 6.89476 over 1

(i.e.) Y = 54.23 * 6.89476 / 1 = 373.9028348 kilopascals

Answer is: 373.9028348 kilopascals are equivalent to 54.23 pounds per square inches.
