Convert pound/square inch [gauge] to millitorr


psig
millitorr

The above form works if you are measuring differential pressure, such as the difference in psi between two points.

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

Note that psig can measure differential pressure in some applications and absolute pressure in others, so you need to know which one fits your calculation.

psig (relative to atmosphere)
millitorr (relative to vacuum)

Common pressure conversions


Definition: Pound/square inch

Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. By contrast, psia measures pressure relative to a vacuum (such as that in space). At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.


Definition: Millitorr

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

So 1 millitorr = 10-3 torrs.

The definition of a torr is as follows:

The torr is a non-SI unit of pressure, named after Evangelista Torricelli. Its symbol is Torr.
