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 92.38 megapascals?
As;
1 megapascals = 145.03806451613 pounds per square inches
92.38 megapascals = Y pounds per square inches
Assuming Y is the answer, and by criss-cross principle;
Y equals 92.38 times 145.03806451613 over 1
(i.e.) Y = 92.38 * 145.03806451613 / 1 = 13398.6164 pounds per square inches
Answer is: 13398.6164 pounds per square inches are equivalent to 92.38 megapascals.
