About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
About Kilolitres per hour
The kilolitre per hour (kL/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, identical to m³/h. It is used interchangeably with m³/h in Australian, New Zealand, and South African process-engineering practice. Pump datasheets from these markets quote capacity in kL/h; water-meter billing in rural areas uses kL/h for irrigation allocation. 1 kL/h = 1 m³/h = 1 000 L/h.
