Volumetric flow
Convert litre per minute (L/min) 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 L/min = 0.06 m³/h
To convert litre per minute to cubic metre per hour, multiply the L/min value by 0.06. To go the other way, divide by 0.06 (or multiply by 16.66667).
| L/min | m³/h |
|---|---|
| 1 | 0.06 |
| 2 | 0.12 |
| 5 | 0.3 |
| 10 | 0.6 |
| 25 | 1.5 |
| 50 | 3 |
| 100 | 6 |
| 250 | 15 |
| 500 | 30 |
| 1000 | 60 |
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 60000 L/min is 3600 m³/h.
Multiply the value in L/min by 0.06 to get m³/h. For example, 10 L/min = 0.6 m³/h.
1 L/min equals 0.06 m³/h.
