What is flow rate?
Flow rate measures the quantity of fluid transported per unit time.
It is essential for pump selection, pipe sizing and process balancing.
m³/h and L/min
Cubic meters per hour are convenient for larger systems, while liters per minute are often easier to read in smaller installations.
Both can be converted through their exact relationship to cubic meters and seconds.
How are flow units converted?
The conversion is based on the relationship between cubic meters and liters together with the relationship between hours and minutes.
One cubic meter per hour equals about 16.6667 liters per minute.
