Volumetric flow
Convert cubic metre per hour (m³/h) to cubic metre per second (m³/s). 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/h = 0.0002777778 m³/s
To convert cubic metre per hour to cubic metre per second, multiply the m³/h value by 0.0002777778. To go the other way, divide by 0.0002777778 (or multiply by 3600).
| m³/h | m³/s |
|---|---|
| 1 | 0.0002777778 |
| 2 | 0.0005555556 |
| 5 | 0.001388889 |
| 10 | 0.002777778 |
| 25 | 0.006944444 |
| 50 | 0.01388889 |
| 100 | 0.02777778 |

| 1000 | 0.2777778 |
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 3600 m³/h is 1 m³/s.
Multiply the value in m³/h by 0.0002777778 to get m³/s. For example, 10 m³/h = 0.002777778 m³/s.
1 m³/h equals 0.0002777778 m³/s.
