Liter per Minute (L/min)
The litre per minute (L/min, LPM) is a flow of one litre each minute, 1/60 000 m³/s.
Symbol: L/min
Quantity: volumetric flow rate (volume per unit time)
SI relation: 1 L/min = 0.00001666666666667 m³/s (exact)
Derivation: 1 L/min = 10⁻³ m³ ÷ 60 s
Exact: yes, by definition
Typical uses
- Medical oxygen and anaesthesia gas flow
- Filter media and respirator testing (32 L/min, 85 L/min)
- Air samplers and lab gas supply
- Pumps, taps and shower heads
