How to Convert Liter/Hour to Cubic Meter/Second

To convert from Liter/Hour (L/h) to Cubic Meter/Second (m³/s), multiply the value by 2.777778e-7.

Formula: m³/s = L/h × 2.777778e-7

Reverse: L/h = m³/s × 3,600,000

Step-by-Step Example

Start with your value in Liter/Hour. For example: 5 L/h
Multiply by the conversion factor: 5 x 2.777778e-7
The result is: 1.388889e-6 m³/s

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.

About Cubic Meter/Second

The cubic meter/second (m³/s) is a unit of flow rate. One cubic meter/second equals 1 base unit. 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.
