The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The definition of a pascal is as follows: The SI prefix "mega" represents a factor of Psi to MPa, or enter any two units below: Enter two units to convert From:

The user only needs to learn how to use the calculator, particularly data input, and how to read the results of the calculations.You can do the reverse unit conversion from Besides, there are numerous psi to MPa calculators out there that can help in the conversion. The conversions are also relevant when you are measuring absolute pressure and you are assuming that the measurements are in Psi. Example of differential pressure measurement is determination of Psi between two points. The corresponding US customary and imperial unit is the pound per square inch (Psi), which is common in meteorology.Ĭonversion 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. 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 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. 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. On the earth surface, the standard atmospheric pressure is accurately given as 101.325 kPa. The calculation for psi into Pascal units is as follows: 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. 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. The Psi is the most critical pressure unit in the United States and is typically used in a broad range of applications. Giga-Pascal (1 GPa is equivalent 1, 000, 000, 000 Pa)īy definition, 1 Psi is one pound of force acting on one square inch.Mega-Pascal (1 MPa is equivalent to 1,000,000 Pa).Kilo-Pascal (1 kPa is equivalent to 1000 Pa).Hecto-Pascal ( 1 hectopascal (1 hPa) is equivalent to 100 Pa).Since pressure gauges give readings in terms of pound force per square inch (psi) and kPa. The pressure gauge reading is usually in pound force per square inch (psi) and kPa (black scale). 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 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. Blaise Pascal was a French physicist, writer, philosopher, mathematician and inventor, who conducted numerous studies on pressure measurements.
Like all other International System of Units (SI) that are usually derived from proper names, the Pascal is named after Pascal’s proper name. The Pascal is the SI unit of pressure, which is named after Blaise Pascal.
