Volumetric flow
Convert litre per minute (L/min) 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 L/min = 60 L/h
To convert litre per minute to litre per hour, multiply the L/min value by 60. To go the other way, divide by 60 (or multiply by 0.01666667).
| L/min | L/h |
|---|---|
| 1 | 60 |
| 2 | 120 |
| 5 | 300 |
| 10 | 600 |
| 25 | 1500 |
| 50 | 3000 |
| 100 | 6000 |
| 250 | 15000 |
| 500 | 30000 |
| 1000 | 60000 |
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 3600000 L/h.
Multiply the value in L/min by 60 to get L/h. For example, 10 L/min = 600 L/h.
1 L/min equals 60 L/h.
