Volumetric flow
Convert cubic metre per second (m³/s) to cubic metre per hour (m³/h). Volumetric flow rate is the volume of fluid passing a point per unit time — the basis for line sizing, pump duty, and instrument ranging.
1 m³/s = 3600 m³/h
To convert cubic metre per second to cubic metre per hour, multiply the m³/s value by 3600. To go the other way, divide by 3600 (or multiply by 0.0002777778).
| m³/s | m³/h |
|---|---|
| 1 | 3600 |
| 2 | 7200 |
| 5 | 18000 |
| 10 | 36000 |
| 25 | 90000 |
| 50 | 180000 |
| 100 | 360000 |
| 250 | 900000 |
| 500 | 1800000 |
| 1000 | 3600000 |
Pump and line duties are quoted in m³/h or US gpm; instrument and utility flows often in L/min or ft³/s.
Volumetric flow depends on temperature and pressure for gases — convert on the same basis (actual vs standard) to avoid errors.
Worked example. A flow rate of 1 m³/s is 3600 m³/h.
Multiply the value in m³/s by 3600 to get m³/h. For example, 10 m³/s = 36000 m³/h.
1 m³/s equals 3600 m³/h.
