About Cubic feet per hour
The cubic foot per hour (ft³/h) equals 0.028316846592/3600 ≈ 7.866×10⁻⁶ m³/s, used in US natural-gas metering (residential gas meters read in cubic feet; billing converts to CCF = 100 ft³) and historical furnace-fuel-consumption tables. A US residential gas furnace consumes 80-200 ft³/h of natural gas at full fire. 1 ft³/h ≈ 7.866×10⁻⁶ m³/s.
About Litres per second
The litre per second (L/s) equals 10⁻³ m³/s, the standard unit for municipal water-supply engineering, fire-fighting flows, and HVAC system air handling. A fire hydrant delivers 15-30 L/s; a household mains water connection is typically 0.1-0.5 L/s; a large building HVAC chilled-water loop circulates 50-200 L/s. 1 L/s = 10⁻³ m³/s = 3.6 m³/h ≈ 15.85 US gal/min.
