How to use this converter
Cubic meters per hour and liters per minute both measure flow rate, common on pumps, ventilation specs and water systems. Use this converter when a datasheet rates flow in m³/h but you size pipework or pumps in L/min. L/min = m³/h × 16.6666667

Frequently Asked Questions
How do I convert m³/h to L/min manually?
Multiply the m³/h value by 16.667. For example, 6 m³/h × 16.667 = 100 L/min. This works because 1 m³ = 1,000 liters and there are 60 minutes in an hour, so the factor is 1000 ÷ 60 ≈ 16.667.
What is a typical pump flow rate in L/min?
Domestic water pumps typically deliver 20–80 L/min. Pool circulation pumps range from 100–400 L/min depending on pool volume. Industrial process pumps can exceed 10,000 L/min. Check the pump's datasheet — manufacturers usually list rated flow at a specific head pressure.
When should I use L/min instead of m³/h?
Use L/min for plumbing, laboratory equipment, medical devices, and small pumps where flow rates are under a few hundred liters per minute. m³/h is preferred for HVAC, industrial processes, and large ventilation systems where the numbers would be unwieldy in L/min.
