Convert Cubic metres per hour to Litres per hour
Convert Cubic metres per hour (m³/h) to Litres per hour (L/h) instantly and accurately.
Conversion Formula
L/h = m³/h × 1000
About Cubic metres per hour
The cubic metre per hour (m³/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, the dominant volumetric flow unit in European process engineering, HVAC, and water treatment. Pump datasheet curves, heat-exchanger sizing software, and wastewater-treatment design all use m³/h as the standard. A domestic water pump runs at 3-8 m³/h; a municipal WWTP inlet pump handles 500-5 000 m³/h. 1 m³/h ≈ 2.778×10⁻⁴ m³/s = 1 000 L/h.
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.
