1 kPA = 0.1450377 PSI

therefore...
72 kPA = 10.4 PSI
83 kPA = 12.0 PSI

Try this unit converter... it is free and has most types of units.

I think you have you "points" (decimals) in the wrong spots
1.0 Bar = 14.7 psi
.72 bar = 10.5
.83 bar = 12.2

1 bar is more then .72 so your conversion should say
"1 Kg/Cm2 = 14.50377 PSI" not "0.1450377"

To get your conversion just times the Kg/Cm2 (bar) by 14.7psi (at least that what i have always been told). thats why my numbers are a lil different then yours.

Acctually maybe im doing something wrong here compared to what you need as im using Kg/Cm2 instead of Kpa or are they the same?

They are not the same:
1kPA = 0.0102 Kg/cm2

also 1 Bar is not 1 Kg/cm2:
1 Bar = 1.020 Kg/cm2

1 Bar is exactly 100 kPA.
