How to Convert Liter/Second to Cubic Meter/Second

To convert from Liter/Second (L/s) to Cubic Meter/Second (m³/s), multiply the value by 0.001.

Formula: m³/s = L/s × 0.001

Reverse: L/s = m³/s × 1,000

Step-by-Step Example

Start with your value in Liter/Second. For example: 5 L/s
Multiply by the conversion factor: 5 x 0.001
The result is: 0.005 m³/s

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 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.
