How to Convert Liter/Second to Liter/Hour

To convert from Liter/Second (L/s) to Liter/Hour (L/h), multiply the value by 3,600.

Formula: L/h = L/s × 3,600

Reverse: L/s = L/h × 0.0002777778

Step-by-Step Example

Start with your value in Liter/Second. For example: 5 L/s
Multiply by the conversion factor: 5 x 3,600
The result is: 18,000 L/h

About Liter/Second

The liter/second (L/s) is a unit of flow rate. One liter/second equals 0.001 base units. UnitConvertLab converts it against every other flow rate unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: flow rate calculations, engineering and science, education.

About Liter/Hour

The liter/hour (L/h) is a unit of flow rate. One liter/hour equals 2.777778 × 10^-7 base units. UnitConvertLab converts it against every other flow rate unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: flow rate calculations, engineering and science, education.
