CFM to PSI Calculator – Accurate Conversions

This tool converts airflow from cubic feet per minute (cfm) to pressure in pounds per square inch (psi) for you.




Results:

How to use:

  • Enter the CFM (Cubic Feet per Minute) of the airflow.
  • Enter the efficiency of the pump as a percentage (0 to 100).
  • Enter the temperature in Fahrenheit.
  • Click the ‘Calculate’ button to see the results.

Explanation:

This calculator converts CFM to PSI based on the values of airflow, pump efficiency, and temperature. The pressure in PSI is calculated using the formula:

pressure (psi) = (cfm * efficiency / 100) / (459.67 + temperature)

where:

  • CFM: Cubic Feet per Minute, the volume of airflow.
  • Efficiency: The efficiency of the pump as a percentage.
  • Temperature: The temperature in Fahrenheit.

Limitations:

  • The calculator assumes ideal conditions and does not take into account other losses or factors that may affect the actual PSI output.
  • The calculation formula used is simplified and hypothetical for demonstration purposes.
  • Efficiency should be a positive number between 0 and 100.
  • Temperature should be in the positive range for realistic measurements.
