The % of vacuum is a relative value where pressure at normal or standard atmosphere is the base value.. p v% = 100% - (p v / p atm) 100% (1). At a 5000-ft elevation, that same pump can achieve 83.4% of 25 in.-Hg - or a vacuum of 20.85 in.-Hg.

Vacuum is commonly measured relative to atmospheric pressure, and represents a negative gauge pressure but still a positive absolute pressure.

The 10 Pa "ultimate" vacuum is in absolute units, not gauge, and is about 0.003 inches Hg. Pa=N/m² : The Pascal (Pa) is the SI unit, 1 Bar = 10E5.Pa = 101 kPa = 0.1 MPa A pressure of 1 Pa applied on a surface A=1m² generates a force F=1N (1N=1 kg.m.s-²). 0000000932 00000 n As vacuum technology advanced, it became necessary to have a more precise vacuum measurement unit than the mm of Hg.
