Convert Cubic feet per day to US gallons per hour
Convert Cubic feet per day (ft³/d) to US gallons per hour (gph) instantly and accurately.
Conversion Formula
gph = ft³/d × 0.3116883117
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 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.
