Simply enter your psi value in the box then click on Convert Megapascal (MPa) To psi (Pound force per square inch) Conversion

So you want to know how many megapascals in a psi ?

Megapascal (MPa) is a metric pressure unit and equals to 1 000 000 force of newton per square meter which is know as a Pascal. 1 MPa equals to 10 Bar. Because of its high pressure ratings is often used in hydraulic and simular systems.

• Use if you want to Convert pound/square inch to megapascal
• Use if you are between two points.
• Or Use for absolute pressure, if measuring psia

## Pound per square inch: The extensively used pressure unit in many countries Pound-per-square-inch (abbreviated as PSI) is a unit of pressure, which measures the quantity of pressure per square inch of area. It is defined as the pressure of a force of 1 pound applied homogeneously above an area of 1 sq inch. Pound or pound force per square inch (psi, pfsi, lb/in², or lbf/in²) is a commonly used British plus American unit of measurement for pressure. (1 psi = 6,894.76 Pascal).

PSI unit is used widely in several countries. In the USA the PSI unit of pressure is the principal unit of measurement for pressure and nearly all instruments of pressure measurement are detailed and display in pounds per square inch. In the UK the PSI unit is still extensively used, but the bar has mostly taken its place as the prime pressure unit. Learn how to convert psi to Mpa

In order to change a measurement that is in PSI to another unit, just multiply it by the applicable pressure conversion factor. Alternatively, if you want to convert a measurement which is in any other pressure unit to PSI, you'll have to divide it by the appropriate pressure conversion factor. You can convert from a psi pressure value to some other unit by making use of the psi conversion table. In the Internet you can find many converters which give you the converted value if you give the corresponding value psi to change another unit or vice versa.

While the PSI unit is used to measure the ambient atmospheric pressure, the pound per square inch absolute (abbreviated as psia) unit s used to measure the relative pressure in vacuum. As the normal relative atmospheric pressure at sea level is equal to about 14.7 PSI, this value will be added to any pressure reading taken in the air at sea level. The typical human blood pressure (120/80 hg/dl) is approximately equal to 2.32 PSI/1.55 PSI, and the normal pressure in a vehicular tire is 32 PSI.
