Units of measure
In the international system (SI) the physical and technical units are validated as follows :
One Pascal corresponds at the pressure of 1 Newton to act on the area of 1 m².
Unit Pa is a very low value and for the standard industrial is used the
Bar (symbol bar) = 0.1 MegaPascal (symbol Mpa=1.000.000 Pa).
The conversion from the old unit of measure to the new one SI is the following:1 Kp/cm² = 0,981 bar
1 bar = 1,02 Kp/cm²The conversion in the SI unit is possible also in the countries
where is not yet used the metric system.
Conversion:1 bar = 14,50 psi
1 psi = 0,07 bar =7.000 Pa
