**Definitions:**

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

**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.

## How to Convert Pascals to Pounds Per Square Inches

*Example: How many pounds per square inches are equivalent to 14.06 pascals?*

As;

1 pascals = 0.000145038 pounds per square inches

14.06 pascals = Y pounds per square inches

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

Y equals 14.06 times 0.000145038 over 1

(i.e.) Y = 14.06 * 0.000145038 / 1 = 0.00203923428 pounds per square inches

Answer is: 0.00203923428 pounds per square inches are equivalent to 14.06 pascals.
