Millitorr is a very small pressure unit used for high vacuum measurements and is a 1/1000x multiple of the Torr pressure unit. 1 mTorr equals 0.133322 pascals.
The millitorr is not a commonly used pressure unit and tends to be used in scientific research or specialised manufacturing fields where very high vacuum pressures are measured.
Please use the list below to find the conversion factor from torr into another pressure unit.

What does 10 millitorr equal in inHg gauge?
The gauge reference does not influence the conversion unless the other pressure value does not have the same pressure reference.
10 mTorr = 0.00393701 inHg
- 1 bar vacuum gauge and sensor with USB plus Labview driver
- Vacuum sensor control system set-point tester for 0 to -0.95 bar/13.8 psi
- -1 to 20 bar g compound range IS 4-20mA propane pressure sensor for process control use
- Negative 500 mmH2O g range 4-20mA output pressure sensor
