Volumetric flow
Convert cubic metre per hour (m³/h) to litre per hour (L/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/h = 1000 L/h
To convert cubic metre per hour to litre per hour, multiply the m³/h value by 1000. To go the other way, divide by 1000 (or multiply by 0.001).
| m³/h | L/h |
|---|---|
| 1 | 1000 |
| 2 | 2000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |
| 250 | 250000 |
| 500 | 500000 |
| 1000 | 1000000 |
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 3600000 L/h.
Multiply the value in m³/h by 1000 to get L/h. For example, 10 m³/h = 10000 L/h.
1 m³/h equals 1000 L/h.
