Convert Cubic inches per minute to Cubic feet per minute
Convert Cubic inches per minute (in³/min) to Cubic feet per minute (ft³/min) instantly and accurately.
Conversion Formula
ft³/min = in³/min × 0.0005787037037
About Cubic inches per minute
The cubic inch per minute (in³/min) equals 1.6387064×10⁻⁵/60 ≈ 2.731×10⁻⁷ m³/s, common in US pneumatic and hydraulic circuit design. Air-tool consumption is rated in SCIM (standard cubic inches per minute); small hydraulic cylinders advancing at 10 in/min with 1 in² bore consume 10 in³/min: exactly 0.163 mL/s. 1 in³/min ≈ 2.731×10⁻⁷ m³/s.
About Cubic feet per minute
The cubic foot per minute (cfm or ft³/min) equals 0.028316846592/60 ≈ 4.719×10⁻⁴ m³/s, the dominant unit for ventilation, HVAC airflow, and compressed-air system design in the US. ASHRAE ventilation standards, building-code fresh-air requirements, and dust-collector capacity are all stated in cfm. A residential HVAC system moves 800-1 200 cfm; an industrial dust collector handles 2 000-20 000 cfm. 1 cfm ≈ 0.4719 L/s.
