Conversion Formula
L/h = gal/s × 13627.48242
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 Litres per hour
The litre per hour (L/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ m³/s, widely used in automotive fuel consumption (L/h), irrigation drip systems, and small pump specifications. A fuel cell vehicle running on hydrogen consumes ±2 L/h of liquid equivalent; a domestic water softener regeneration cycle uses 40-100 L/h of brine. 1 L/h ≈ 2.778×10⁻⁷ m³/s ≈ 0.2642 US gal/h.
