About Cubic feet per day
The cubic foot per day (ft³/d) equals 0.028316846592/86400 ≈ 3.277×10⁻⁷ m³/s, found in US oil-and-gas production reports for low-rate gas wells and groundwater monitoring wells. A marginal coalbed-methane well producing 50 Mcf/d (50 000 ft³/d) of gas represents a modest but economic flow; residential water-well yield tests report in ft³/d. 1 ft³/d ≈ 3.277×10⁻⁷ 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.
