vacuum can be divided into 4:
coarse vacuum ( RV) : 1000 - 1 mbar
in vacuum, MV) : 1 - 10 - 3 mbar
high vacuum ( HV) : < 10- 3 - 10 - 7 mbar
ultra high vacuum ( 特高压) : < 10- 7 mbar
Vacuum unit of measure:
pharmaceutical units: + 100 Pa Pa 1 mbar = = 1 mbar hPa
other units: N/m squared 1 N/m squared = 1 Pa = 0,01 mbar
1 Torr = 1 Torr 33 mbar
1 mmHG = 1 Torr = 1 mmHG 33 mbar
Atmosphere 1 ATM = 1013 mbar
to Micron 1 mu = 0001 Torr = 0001 33 mbar
PSI 1 PSI = 0069 bar
% 1% Vacuum Vacuum = 10 mbar
