Pressure Reference

Useful decontamination validation engineering reference for pressure.

Pressure Units & Conversion

Units of Pressure
Bar Gauge  =  Bar G
Millibar Gauge = Mbar G
Bar Absolute = Bar A
Millibar Absolute = Mbar A
Pascal = Pa
Kilopascal = kPa
Pound per Square Inch = psi
Kilonewton per square metre = kN/m2
 
Pressure Conversion
1 bar = 100 kPa
1 bar = 14.5 psi
1 psi = 6.89 kPa
1 psi = 0.0689 bar G
1 kPa = 0.145 psi
1 ft H20 = 29.837 mbar
1 ft H20 = 2.989 kPa (2.989 kN/m2
1 ft H20 = 0.305m H20
1 m H20 = 98.0067 mbar
1 mbar = 0.4015 in H20
