Conversions
Choosing The Correct Sized Tubing
Pressure, Flow and Volume
These tables list conversion factors for the most common pressure, flow and volume units used in vacuum technology.
To convert, multiply the unit you convert to by the quantity of the unit you are converting from. For example, to convert
PSI to mbar, multiply by 68.948 – therefore, 15 PSI = 15 * 68.948 = 1034.2 mbar.
