About flow rate units
Flow rate is volume per unit time. Plumbing and pumps are rated in litres per minute or US gallons per minute, ventilation in cubic metres per hour or cubic feet per minute, and river discharge in cubic metres per second.
These are volumetric flow rates. US and Imperial gallons per minute differ; gas volumes quoted at standard conditions also need their reference temperature and pressure before comparison with actual flow.
