pound/square inch

The above form works if you are measuring differential pressure, such as the difference in psi between two points. It also gives the correct answer for absolute pressure, assuming you are measuring psia, which is the pressure relative to absolute zero vacuum.

If you are measuring relative to vacuum and want to resolve the pressure relative to the atmosphere, then you should use the form below.

pound/square inch (relative to atmosphere)
kilopascal (relative to vacuum)

›› Definition: Pound/square inch

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

›› Definition: Kilopascal

The SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.

So 1 kilopascal = 103 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.
