Compressed Air Conversion Formulas

 

Flow rates - CFM / l/min / M3/hr

1 CFM = 28.328 l / min
1 CFM = 1.699 M3 / hr
1 M3 / hr = 0.58857 CFM
1 M3 / hr = 16.667 l / min
1 l / min = 0.0353 CFM
1 l / min = 0.06 M3 / hr


Pressure - bar / psi / mbar / kPa

1 bar = 14.5 psi
1 bar = 1000 mbar
1 bar = 100 kPa
1 psi = 0.06895 bar
1 psi = 68.95 mbar
1 psi = 6.895 kPA

1 mbar = 0.001 bar

1 kPA = 0.01 bar


Volumes - litre / gallon / M3

1 litre = 0.219969 gallon
1 litre = 0.001 M3
1 gallon = 4.54609 litre
1 gallon = 0.004546 M3
1 M3 = 1000 litres
1 M3 = 219.969 gallon


Electrical Power - KW / HP

1 KW = 1.341 HP
1 HP = 0.746 KW
Heat Dissipation - KW - Btu/h

1 KW = 3412.14 Btu/h
1 Btu/h = 0.000293 KW
