A cubic metre per second (m³·s⁻¹, m³/s, cumecs or cubic meter per second in American English) is a derived SI unit of flow rate equal to that of a cube with sides of one metre (~39.37 in) 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.
