Pressure And Leakage Unit Conversion Table
Dec 16, 2021| Pressure and leakage unit conversion table
The unit of pressure in the SI system is Pa (Pascals). A pressure in Pa is a force of 1N (Newtons) on 1m2 of area. The conversion of Pa to other units is shown in Table C-1.
Table C-1 Conversion of pressure units
Pa | Torr | mbar | bar | atm | |
1Pa | 1 | 0.75×10-2 | 0.01 | 10-5 | 0.99×10-5 |
1 Torr | 133 | 1 | 1.33 | 1.33×10-3 | 1.32×10-3 |
1 mbar | 100 | 0.75 | 1 | 10-3 | 0.99×10-3 |
1 bar | 105 | 750 | 1000 | 1 | 0.99 |
1 atm | 1.013×105 | 760 | 1013 | 1.013 | 1 |
In the SI system of units, the unit of leakage rate is Pa·m3/s. The conversion of this unit to other units is shown in Table C-2.
Table C-2 Conversion of leakage rate units
Pa×m3/s | Torr·L/S | mbar·L/S | atm·mL/S | |
1 Pa·m3/s | 1 | 7.5 | 10 | 9.9 |
1 Torr·L/S | 0.133 | 1 | 1.33 | 1.32 |
1 mbar·L/S | 0.1 | 0.75 | 1 | 0.99 |
1 atm·mL/S | 0.101 | 0.76 | 1.01 | 1 |
