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 |
