Convert MPa to psi

The calculator allows you to convert MPa (megapascal) to psi (pounds per inch square).

Perform the reverse calculation: convert psi to MPa

1 MPa = 145.0377 psi (approximately egal to)
1 psi = 0.00689476 MPa (approximately egal to)

To convert MPa to psi, multiply by 145.0377.

Example 1

We are going to convert a pressure p of 5 MPa to pounds per inch square (psi).
Pressure p = 5 MPa
1 MPa = 145.0377 psi (approximately egal to)
p = 5 MPa = 5 x 145.037 = 725.19 MPa (approximately egal to)

Example 2: convert 8 MPa to psi

8 MPa x 145.0377 = 1160.30 psi

Example 3: convert 15 MPa to psi

15 MPa x 145.0377 = 2175.57 psi

MPa (megapascal)

The megapascal (MPa) is a unit of pressure in the International System of Units (SI). It is defined as one million pascal (Pa). One megapascal is roughly equivalent to 145 pounds per square inch (psi). The symbol for the megapascal is "MPa". The Pascal (Pa) is the SI unit of pressure, and it is defined as one Newton of force per square meter of area. This means that a pressure of one Pascal is produced by a force of one Newton acting on an area of one square meter. The Pascal unit of pressure is named after Blaise Pascal, a French mathematician, physicist and philosopher.

Psi (pound per inch square)

Psi stands for "pounds per square inch" which is a unit of pressure. It is defined as the pressure exerted by a force of one pound-force applied to an area of one square inch.

Pressure is a physical quantity that is commonly measured using various units of measurement. Pressure is defined as the force applied per unit area, and is expressed in units such as pascal (Pa), bar, pounds per square inch (psi), and atmosphere (atm), among others.
