About the CFM to cL/min Converter

This converter changes a flow rate entered in cubic feet per minute into centiliters per minute and also shows related metric flow units. It is useful for ventilation, airflow, pump, and fluid-flow calculations where CFM must be compared with metric units.

How to use this calculator

  1. Enter the flow rate in the CFM input field.
  2. Set the number of decimal places to display.
  3. Read the converted value in cL/min.
  4. Check the additional results in L/min, mL/min, and m³/h.
  5. Use a non-negative CFM value; negative or invalid entries will not calculate.

How it works

The calculator uses cubic feet per minute as the input flow rate. One cubic foot is defined as 28.316846592 liters, which is equal to 2,831.6846592 centiliters.

To convert CFM to cL/min, the calculator multiplies the CFM value by 2,831.6846592. It also calculates liters per minute by multiplying by 28.316846592, milliliters per minute by multiplying by 28,316.846592, and cubic meters per hour by multiplying cubic meters per minute by 60.

The decimal places setting only controls rounding in the displayed results. The conversion assumes the international foot definition and does not adjust for temperature, pressure, gas density, or measurement conditions.

Example calculation

For an input of 1 CFM with 2 decimal places, the main conversion is 1 × 2,831.6846592 = 2,831.68 cL/min. The related outputs are 28.32 L/min, 28,316.85 mL/min, and 1.70 m³/h.

Frequently asked questions

How many cL/min are in 1 CFM?

1 CFM equals 2,831.6846592 cL/min, commonly rounded to 2,831.68 cL/min.

What formula converts CFM to cL/min?

Multiply the CFM value by 2,831.6846592 to get centiliters per minute.

Does changing decimal places change the conversion?

No. Decimal places only change how many digits are shown after rounding; the underlying conversion factor stays the same.

Can I enter negative CFM?

No. The calculator only accepts valid non-negative CFM values because a standard flow-rate magnitude is being converted.

Is CFM a gas-only unit?

CFM is often used for airflow, but it is a volume flow-rate unit and can represent any fluid volume per minute if the measurement is appropriate.
