Unit definition
Litres per second (L/s) One litres per second equals 0.001 cubic metre per second.
Unit history
Litres per second is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert L/s to cubic metre per second.
3. Convert the base value to m³/h and apply your display precision.
Understand the result before using it
Litres per second to Cubic metres per hour converts a value measured in Litres per second (L/s) into the equivalent value in Cubic metres per hour (m³/h). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.001 ÷ 0.0002777777777777778
Assumptions
- Litres per second and Cubic metres per hour represent the same flow rate quantity.
- The input is expressed in L/s; the output is expressed in m³/h.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 L/s = 3.6 m³/h. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a L/s measurement in a document that expects m³/h.
- Compare a litres per second value with a value reported in cubic metres per hour.
- Check the L/s-to-m³/h arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse L/s with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Litres per second to Cubic metres per hour?
result = input × 0.001 ÷ 0.0002777777777777778 Using the displayed relationship, 1 L/s equals 3.6 m³/h.
How many Cubic metres per hour are in one Litres per second?
One Litres per second is 3.6 Cubic metres per hour. The displayed digits may be rounded.
Can I reverse the L/s to m³/h conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts m³/h back to L/s.
Is the Litres per second to Cubic metres per hour result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
