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 US gallons per second
The US gallon per second (gal/s) equals 3.785411784×10⁻³ m³/s, used for very large pump discharge rates and fire-suppression deluge systems. A large centrifugal fire pump rated 1 500 US gal/min delivers exactly 25 US gal/s; industrial cooling-tower makeup lines are sized in gal/s at peak demand. 1 US gal/s = 3.785411784×10⁻³ m³/s = 60 US gal/min ≈ 227.1 L/min.
