Pump Flow Rate Converter
Convert flow rate from litres per minute to litres per second and cubic metres per hour without changing the underlying rate.
How to use this calculator
- Enter a non-negative flow rate in litres per minute.
- Confirm that all inputs use the stated units and the same population, period or scope.
- Change one assumption at a time when comparing scenarios.
Formula used by the pump flow rate converter calculator
L/s = L/min ÷ 60; m³/h = L/min × 0.06
- L/s = L/min ÷ 60; m³/h = L/min × 0.06
- Unit conversion only; it does not account for pump pressure, head, viscosity or pipe loss.
- Inputs are validated against required ranges and outputs are rounded for readability.
Worked examples
Worked example
60 litres per minute.
The equivalent rates are 1 L/s and 3.6 m³/h.
The equivalent rates are 1 L/s and 3.6 m³/h.
Understanding the result
Convert flow rate from litres per minute to litres per second and cubic metres per hour without changing the underlying rate.
Unit conversion only; it does not account for pump pressure, head, viscosity or pipe loss.
Important notes
Unit conversion only; it does not account for pump pressure, head, viscosity or pipe loss.
Use the result as a calculation aid for the inputs supplied; confirm critical specifications independently.
Frequently asked questions
Are the units interchangeable?
They describe the same volume per unit time using different scale factors.
Does this select a pump?
No; pump selection also requires pressure/head and operating conditions.
