Convert US gallons per minute to Kilolitres per second
Convert US gallons per minute (gpm) to Kilolitres per second (kL/s) instantly and accurately.
Conversion Formula
kL/s = gpm × 6.309019640e-5
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 second
The kilolitre per second (kL/s) equals 1 m³/s, so 1 kL/s is identical to 1 m³/s. The term kilolitre is favoured in Australian and South African engineering over the equivalent cubic metre per second. Municipal water-main flow and stormwater-channel capacity are sometimes expressed in kL/s in these countries. 1 kL/s = 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min.
