Convert millihg to pound/square inch


millihg
PSI

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.

millihg (relative to vacuum)
PSI (relative to atmosphere)

Common pressure conversions


Definition: Millihg

The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.

So 1 millihg = 10-3 hg.


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.
