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 metres per minute

The cubic metre per minute (m³/min) equals 1/60 m³/s ≈ 1.667×10⁻² m³/s, used in large compressor and blower specifications, tunnel ventilation design, and industrial air-handling. A mine-ventilation fan may move 1 000-5 000 m³/min; an industrial rotary-screw compressor delivers 5-50 m³/min of free air. 1 m³/min = 1 000 L/min ≈ 35.31 ft³/min ≈ 264.2 US gal/min.
