Reverse Factor

1 m³/s = 3600 m³/hr

Worked Example

Convert 25 Cubic meters per hour to Cubic meters per second: 25 m³/hr = 0.00694444 m³/s

About Cubic meter per hour (m³/hr)

A metric flow-rate unit equal to 1/3,600 m³/s. m³/hr is the standard unit for industrial process flows, HVAC air handling, pump sizing in European specifications, natural-gas metering, and municipal water treatment capacity. European building-code air-exchange requirements and pump curves are almost always expressed in m³/hr.

About Cubic meter per second (m³/s)

The SI unit of volumetric flow rate — the volume of fluid passing a given point per unit time. m³/s is the universal unit in fluid-dynamics research, large-pipeline engineering, river and flood hydrology, and industrial process flow. Also called the "cumec" in hydrology. The Amazon River discharge is ~209,000 m³/s. Most practical applications use smaller units like L/s or m³/hr because m³/s values are typically very small (a household faucet is ~0.0002 m³/s).
