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 1.34 megapascals?
As;
1 megapascals = 145.03806451613 pounds per square inches
1.34 megapascals = Y pounds per square inches
Assuming Y is the answer, and by criss-cross principle;
Y equals 1.34 times 145.03806451613 over 1
(i.e.) Y = 1.34 * 145.03806451613 / 1 = 194.35100645161 pounds per square inches
Answer is: 194.35100645161 pounds per square inches are equivalent to 1.34 megapascals.
