**Definitions:**

**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.

**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 Megapascals to Pounds Per Square Inches

*Example: How many pounds per square inches are equivalent to 25.69 megapascals?*

As;

1 megapascals = 145.03806451613 pounds per square inches

25.69 megapascals = Y pounds per square inches

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

Y equals 25.69 times 145.03806451613 over 1

(i.e.) Y = 25.69 * 145.03806451613 / 1 = 3726.0278774194 pounds per square inches

Answer is: 3726.0278774194 pounds per square inches are equivalent to 25.69 megapascals.
