Below you will find conversion formulas for all aspects of compressed air installations including flow, volume and pressure. If you have any queries or you need some expert advice on sizing a compressor for your application please don’t hesitate to contact us.
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
