A cubic metre per second (m³s⁻¹, m³/s, cumecs or cubic meter per second in American English) is a derived SI unit of volumetric flow rate equal to that of a stere or 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.

The cubic foot per second (symbol: ft³/s) is a the unit of volumetric flow rate equal to that of a cubic foot moving each second. It is equal 0.028316846592 m³/s.
