Convert psia to MPa

How many psia in 1 MPa? The answer is 145.03773800722. We assume you are converting between pound/square inch [absolute] and megapascal. You can view more details on each measurement unit: psia or MPa The SI derived unit for pressure is the pascal. 1 pascal is equal to 0.00014503773800722 psia, or 1.0E-6 MPa. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between pounds/square inch and megapascals. Type in your own numbers in the form to convert the units!

1 psia to MPa = 0.00689 MPa

10 psia to MPa = 0.06895 MPa

50 psia to MPa = 0.34474 MPa

100 psia to MPa = 0.68948 MPa

200 psia to MPa = 1.37895 MPa

500 psia to MPa = 3.44738 MPa

1000 psia to MPa = 6.89476 MPa

You can do the reverse unit conversion from MPa to psia, or enter any two units below:

Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.

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

So 1 megapascal = 106 pascals.

The definition of a pascal is as follows:

The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.
