Convert US gallons per second to Kilolitres per hour
Convert US gallons per second (gal/s) to Kilolitres per hour (kL/h) instantly and accurately.
Conversion Formula
kL/h = gal/s × 13.62748242
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.
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.
