Convert US gallons per hour to Cubic feet per hour
Convert US gallons per hour (gph) to Cubic feet per hour (ft³/h) instantly and accurately.
Conversion Formula
ft³/h = gph × 0.1336805556
About US gallons per hour
The US gallon per hour (gph) equals 3.785411784×10⁻³/3600 ≈ 1.051×10⁻⁶ m³/s, common in oil-burner nozzle ratings, water-softener regeneration, and RV/marine-plumbing specifications. Residential oil-burner nozzles are rated in gph (e.g., 0.75 gph, 1.00 gph); a small boat bilge pump might handle 200-500 gph. 1 US gph ≈ 1.052×10⁻⁶ m³/s ≈ 3.785 L/h.
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.
