**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.

**Megapascal** (abbreviations: **Mpa, or MN/m2, or N/mm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one meganewton per square meter or one newton per square millimeter. It is named after the French polymath Blaise Pascal.

## How to Convert Pounds Per Square Inches to Megapascals

*Example: How many megapascals are equivalent to 94.1 pounds per square inches?*

As;

1 pounds per square inches = 0.0068947417585595 megapascals

94.1 pounds per square inches = Y megapascals

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

Y equals 94.1 times 0.0068947417585595 over 1

(i.e.) Y = 94.1 * 0.0068947417585595 / 1 = 0.64879519948045 megapascals

Answer is: 0.64879519948045 megapascals are equivalent to 94.1 pounds per square inches.
