Liter per second quick reference
| Liter per second | Gallon (US) per minute | Liter per minute | Cubic meter per second |
|---|---|---|---|
| 1 L/s | ≈ 15.85032314 GPM | = 60 L/min | = 0.001 m³/s |
| 10 L/s | ≈ 158.5032314 GPM | = 600 L/min | = 0.01 m³/s |
| 100 L/s | ≈ 1585.032314 GPM | = 6000 L/min | = 0.1 m³/s |
| 1000 L/s | ≈ 15850.32314 GPM | = 60000 L/min | = 1 m³/s |
Where the liter per second fits
The next smaller flow rate unit is the cubic foot per minute (CFM). 1 L/s ≈ 2.118880003 CFM, and 1 CFM = 0.4719474432 L/s.
The next larger flow rate unit is the cubic meter per minute (m³/min). 1 L/s = 0.06 m³/min, and 1 m³/min ≈ 16.66666667 L/s.
