Litre per second to Cubic metre per hour

Exact answer: 1 l/s = 3.6 m³/h (exact defined factor)

Litre per second and Cubic metre per hour describe the same quantity from the Flow rate family but come from different systems of units. The factor is defined exactly. Flow rate is used in heating, plumbing, process engineering and irrigation.

Examples

010.5 l/s = 1.8 m³/h

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Flow rate is volume per time, not volume. A pipe volume in litres cannot be converted into l/min directly; the time base is required.

03Base unit: m³/s

1 l/s = 0.001 m³/s. Then the value is converted through the base unit m³/s into Cubic metre per hour.
