Formula: m³/h = L/s × 3.6
Multiply any L/s value by 3.6 to get m³/h.
Reverse: L/s = m³/h × 0.2778
Common flow rate values — factor: 1 L/s = 3.6 m³/h

L/s × 3.6 = m³/h.
1 L/s = 3.6 m³/h. 100 L/s = 360 m³/h.
m³/h ÷ 3.6 = L/s.
Designs pumps, pipes, and water distribution systems with flow rates in m³/s, L/s, and GPM.
Specifies air handling units and ductwork in CFM (ft³/min) and m³/h for North American and European projects.
Monitors and controls treatment processes with flow rates in m³/h, L/s, and MGD.
Designs sprinkler systems with required flows in GPM and L/min per NFPA standards.
Measures river and groundwater flows in m³/s (m) and ft³/s (cfs) for flood modeling and water resource planning.
Configures ventilators and oxygen delivery systems with flow rates specified in L/min.
Liters per second (L/s) is widely used in water supply engineering, fire protection, and irrigation where liter-scale flows are practical. One L/s = 0.001 m³/s = 60 L/min.
Fire hoses typically deliver 7–25 L/s. Municipal water distribution systems are designed for flows in L/s. Swimming pool filtration systems run at 1–10 L/s. A garden hose delivers about 0.3 L/s.
Interesting fact: The human heart pumps about 0.083 L/s (5 L/min) at rest, rising to 0.333–0.5 L/s (20–30 L/min) during intense exercise. Over a lifetime, the heart pumps approximately 200 million liters of blood.
Cubic meters per hour (m³/h) is the standard flow unit in European industrial and HVAC specifications, water treatment, and utility metering. It is the most practical scale for many industrial processes.
Water meters in Europe display consumption in m³, and flow rates in municipal water systems are specified in m³/h. A typical home consumes 1–5 m³/h peak demand; a large industrial facility might use 1,000–10,000 m³/h.
Interesting fact: Global freshwater withdrawal for agriculture, industry, and municipal use is approximately 4,600 km³/year — about 524,000 m³/h per billion people — making water flow measurement one of the most economically important metrological applications.
Converting L/s to m³/h is essential across hydraulic engineering, HVAC, water treatment, fire protection, and medicine. SI units (m³/s, L/s) are standard in science; European engineering uses m³/h; US systems use GPM and CFM; medical applications use L/min.
Quick reference: 10 L/s = 36 m³/h. Reverse: 1 m³/h = 0.2778 L/s. Factor: 1 L/s = 3.6 m³/h.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
