Volumetric flow
Convert litre per minute (L/min) to cubic foot per minute (ft³/min). 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 = 0.03531467 ft³/min
To convert litre per minute to cubic foot per minute, multiply the L/min value by 0.03531467. To go the other way, divide by 0.03531467 (or multiply by 28.31685).
| L/min | ft³/min |
|---|---|
| 1 | 0.03531467 |
| 2 | 0.07062933 |
| 5 | 0.1765733 |
| 10 | 0.3531467 |
| 25 | 0.8828667 |
| 50 | 1.765733 |
| 100 | 3.531467 |
| 250 | 8.828667 |
| 500 | 17.65733 |
| 1000 | 35.31467 |
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 2118.88 ft³/min.
Multiply the value in L/min by 0.03531467 to get ft³/min. For example, 10 L/min = 0.3531467 ft³/min.
1 L/min equals 0.03531467 ft³/min.
Pump and line duties are quoted in m³/h or US gpm; instrument and utility flows often in L/min or ft³/s.
