A cubic metre per second (m3·s-1, m3/s or cubic meter per second in American English) is a derived SI unit of flow rate equal to that of a cube with sides one metre (100 centimetres or 39.37 inches) in length exchanged or moving each second. It is popularly used for water flow, especially in rivers and streams, and fractions for HVAC values measuring air flow.
