Convert Litres per hour to Cubic metres per second
Convert Litres per hour (L/h) to Cubic metres per second (m³/s) instantly and accurately.
Conversion Formula
m³/s = L/h × 2.777777778e-7
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.
About Cubic metres per second
The cubic metre per second (m³/s) is the SI coherent unit of volumetric flow rate. It is used for large river discharges, turbine inlet flows, and major pipeline capacities. The Amazon River at its mouth averages ≈200 000 m³/s; a large hydroelectric turbine passes 400-800 m³/s; a major municipal water-main carries 5-20 m³/s. 1 m³/s = 1 000 L/s ≈ 15 850 US gal/min = 35.315 ft³/s.
