Volumetric flow rateexact by definition

The cubic metre per second is the SI unit of volumetric flow rate, the volume passing a point per unit time. It is a large unit for most plumbing work but the natural one for rivers, large pumping stations and ventilation of big structures. The relation to SI base units is exact by definition.
