megapascal [MPa] to pound per square inch [psi] Converter

Quick Reference

1 megapascal (MPa) = 145.0376808 pound per square inch (psi)

1 pound per square inch (psi) = 0.00689476 megapascal (MPa)

How to Convert megapascal to pound per square inch

1 MPa = 145.0376808 psi
1 psi = 0.00689476 MPa

To convert megapascal to pound per square inch, multiply the value by 145.0376808. To convert pound per square inch back to megapascal, divide by 145.0376808.

Example: convert 10 MPa to psi:
10 MPa = 10 x 145.0376808 = 1450.376808 psi

↔ Convert pound per square inch to megapascal

megapascal

Definition: The megapascal (symbol: MPa) is a multiple of the pascal, which is the SI unit of pressure and stress. One MPa is equal to 1,000,000 pascals.

History/origin: Like the pascal, the megapascal's origin is tied to the development of SI units. It provides a more convenient scale for expressing large pressures.

Current use: Megapascals are frequently used in engineering, especially in the fields of material science, structural engineering, and geomechanics, for measuring the strength of materials, stresses in structures, and pressures in geological formations.

pound per square inch

Definition: Pound per square inch (symbol: psi or lbf/in²) is a unit of pressure in the imperial and US customary systems. It is defined as the pressure resulting from a force of one pound-force applied to an area of one square inch.

History/origin: The pound per square inch is rooted in the English system of units. Its widespread use grew with the development of steam engines and other technologies requiring pressure measurements.

Current use: psi is commonly used in the United States for measuring tire pressure, hydraulic pressure, steam pressure, and the pressure of compressed gases. It's prevalent in automotive, manufacturing, and various engineering applications.
