How to Calculate CFM to kW Ratio

To calculate the CFM to kW ratio for an air compressor, you need to know the CFM (Cubic Feet per Minute) and the kW (Kilowatts) ratings. The formula is:

CFM to kW Ratio = CFM ÷ kW

Use the form above to input the CFM and kW values, and the calculator will provide the ratio.

If you're wondering "How many kW is 1 CFM?", a typical stationary air compressor can produce 4 to 6 CFM per 1 kW of power output, depending on the compressor type and efficiency.

Power Output (kW) CFM Output
1 kW 4 - 6 CFM
5 kW 20 - 30 CFM
10 kW 40 - 60 CFM
25 kW 100 - 150 CFM
50 kW 200 - 300 CFM
100 kW 400 - 600 CFM
