Conversion of PSI to MPa

The Pascal is the SI unit of pressure, which is named after Blaise Pascal. Like all other International System of Units (SI) that are usually derived from proper names, the Pascal is named after Pascal’s proper name. Blaise Pascal was a French physicist, writer, philosopher, mathematician and inventor, who conducted numerous studies on pressure measurements. The symbol of Pascal is Pa and the unit is used in measuring internal pressure, Young’s modulus, tensile strength, and stress, among other pressure related units. Pressure is the measure of force that is acting per unit area and is measured in terms of Newton per square meter (N/M2). The pressure gauge reading is usually in pound force per square inch (psi) and kPa (black scale). 

Since pressure gauges give readings in terms of pound force per square inch (psi) and kPa. The common multiples of the Pascal are:

  • Hecto-Pascal ( 1 hectopascal (1 hPa) is equivalent to 100 Pa)
  • Kilo-Pascal (1 kPa is equivalent to 1000 Pa)
  • Mega-Pascal (1 MPa is equivalent to 1,000,000 Pa)
  • Giga-Pascal (1 GPa is equivalent 1, 000, 000, 000 Pa)

Converting Psi to MPa

By definition, 1 Psi is one pound of force acting on one square inch. The Psi is the most critical pressure unit in the United States and is typically used in a broad range of applications. Since the Megapascal (MPa) is the unit of pressure that is frequently used in hydraulic systems and machines because of its high pressure ratings, it is critical to know how to convert Psi to MPa. How many units of Psi are equivalent to 1 MPa? Since one pound square inch (Psi) is equivalent to 6 894.75729 Pascal, then 1 Psi is equivalent to 0.00689475729 Megapascal.

1Pa = 1 N/m^2 therefore 1 MPa
= 10^6 N/m^2 

1psi = 0.4536 x 9.81 N/in^2 
= 0.4536 x 9.81 x 10^4 / (2.54)^2 N/m^2 
= 6897. N/m^2 

Therefore 1 MPa = 10^6 / 6897.
= 144.99 psi

The calculation for psi into Pascal units is as follows:

1 Pa = 1 Pascals (Pa)
1 psi = 6894.76 Pascals (Pa)

Pa value x 1 Pa = psi value x 6894.76 Pa
Pa value = psi value x 6894.76

On the earth surface, the standard atmospheric pressure is accurately given as 101.325 kPa. Barometric pressure reports by meteorologists usually give the pressure in hectopascal while the kilopascal is commonly used to report pressure in inflation guidance markings for bicycle tires. The hectopascal usually corresponds to an atmospheric pressure of 0.1% just slightly above the sea level, while one kilopascal corresponds to about 1% atmospheric pressure. One hectopascal is also equivalent to one millibar while one standard atmospheric pressure corresponds to 101325 Pa, 1013.25 hPa, or 101.325 kPa. The corresponding US customary and imperial unit is the pound per square inch (Psi), which is common in meteorology.

Conversion of Psi to MPa is crucial when working with Psi units or differential pressure and there arises a need to convert the pressure to MPa. Example of differential pressure measurement is determination of Psi between two points. The conversions are also relevant when you are measuring absolute pressure and you are assuming that the measurements are in Psi. Besides, there are numerous psi to MPa calculators out there that can help in the conversion. The user only needs to learn how to use the calculator, particularly data input, and how to read the results of the calculations.
