Convert Cubic Centimeters per Minute to CFM

Formula

CFM = cm³/min × 0.00003531466672149

or CFM = cm³/min ÷ 28316.846592

Derivation from SI units:

• 1 cm³/min = 10⁻⁶ m³ ÷ 60 s
• 1 CFM = (0.3048 m)³ ÷ 60 s = 4.719474432 × 10⁻⁴ m³/s
• 1 cm³/min = 1.666666666667 × 10⁻⁸ m³/s ÷ 0.0004719474432 m³/s per CFM = 0.00003531466672149 CFM

Both units are defined exactly, so the factor is exact. Cubic Centimeter per Minute definition: cubic centimeter per minute; Cubic Foot per Minute definition: cubic foot per minute.

Worked examples

1. A reading of 5 cm³/min converts to 0.0001765733336 CFM.
   5 cm³/min × 0.00003531466672 = 0.0001765733336 CFM
2. A value of 200 cm³/min is 0.007062933344 CFM.
   200 cm³/min × 0.00003531466672 = 0.007062933344 CFM

Where it's used

Cubic Centimeters per Minute are used for chromatography carrier-gas and HPLC flows, while cubic feet per minute appear in US HVAC airflow (about 400 CFM per ton of cooling). Both measure volumetric flow rate (volume per unit time), so the conversion is a fixed factor.
