 what's kPa?


[Your question obviously references the chart attached to Matt's post... kPa stands for kiloPascal.  If you're looking for a conversion, 100 kilopascal = 29.5299831 inch of mercury [0 °C].  Go to http://www.onlineconversion.com/pressure.htm and poke around... you can convert anything there.                 <Marv>                  ]
