Convert Cubic Feet per Minute to cm³/min

Formula

cm³/min = CFM × 28316.846592

Derivation from SI units:

• 1 CFM = (0.3048 m)³ ÷ 60 s = 4.719474432 × 10⁻⁴ m³/s
• 1 cm³/min = 10⁻⁶ m³ ÷ 60 s
• 1 CFM = 0.0004719474432 m³/s ÷ 1.666666666667 × 10⁻⁸ m³/s per cm³/min = 28316.846592 cm³/min

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

Worked examples

1. A reading of 100 CFM converts to 2831684.659 cm³/min.
   100 CFM × 28316.84659 = 2831684.659 cm³/min
2. A value of 800 CFM is 22653477.27 cm³/min.
   800 CFM × 28316.84659 = 22653477.27 cm³/min

Where it's used

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