PRESSURE:
KPa = Kilopascal, N/m2 = Newton meter squared,
1 KPa = 1000 N/m2 = 0.145 psig = 0.01 BAR = 0.0098 Atm
1 psig = 6.986 KPa = 6896 N/m2 = 0.0689 Bar = 0.0680 Atm
1 MPa = 145.037 psig = 10 Bar
1 Atm = 14.7 psig = 760 mm Hg = 760 Torr = 760,000 millitorr = 760 microns = 101,000 Pascal
1 Torr = 0.00132 Atm = 1 mm Hg
