About US pints per hour
The US pint per hour (pt/h) equals 3.785411784×10⁻³/8/3600 ≈ 1.314×10⁻⁷ m³/s, used in US medical-device standards for slow-drip infusion and in American homebrew calculations for sparge water addition rates. A slow gravity sparge at 24 pt/h = 3 US gal/h is typical for small-batch homebrewing. 1 US pt/h ≈ 1.314×10⁻⁷ 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.
