Learn how to Convert MPa to psi. A MPa (megapascal) is a unit of measurement for pressure. A single pascal (Pa) is a unit of pressure equal to one newton per square meter. Mega means million, therefore one MegaPascal equals 1,000,000 Pascals. You can convert an MPa value to psi(pound-force per square inch) by using a calculator or you can use an online unit conversion calculator.

## The definition of a pascal

The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre and is equivalent to 10 barye (Ba) in the CGS system. The unit of measurement called standard atmosphere (atm) is defined as 101,325 Pa.

Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar. Meteorological observations typically report atmospheric pressure in hectopascals per the recommendation of the World Meteorological Organization. Reports in the United States typically use inches of mercury or millibars, in Canada these reports are given in kilopascals.

Uses

The pascal (Pa) or kilopascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch (psi) unit, except in some countries that still use the imperial measurement system or the US customary system, including the United States.

Geophysicists use the gigapascal (GPa) in measuring or calculating tectonic stresses and pressures within the Earth.

Medical elastography measures tissue stiffness non-invasively with ultrasound or magnetic resonance imaging and often displays Young's modulus or shear modulus of tissue in kilopascals.

In materials science and engineering, the pascal measures the stiffness, tensile strength and compressive strength of materials. In engineering, the megapascal (MPa) is the preferred unit for these uses, because the pascal represents a very small quantity.

The SI prefix "mega" represents a factor of 106, or in exponential notation, 1E6.

So 1 megapascal = 106 pascals.

## Definition: Pound/square inch

The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/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.
