Accuracy and rounding
Use volume-flow conversions only when the fluid volume per time is known; mass flow also depends on density.
Volume-flow units combine fixed volume definitions with fixed time units. U.S. gallons are used when gpm or gph is shown.
For pumps and HVAC, round L/s only after allowing for the equipment tolerance and operating point.
How to convert m³/s to L/s
- Type the m³/s value in the calculator.
- Keep m³/s selected as the from unit and L/s selected as the to unit.
- Use the instant result, or copy it with the copy button.

| m³/s | L/s |
|---|---|
| 1 m³/s | 1,000 L/s |
| 2 m³/s | 2,000 L/s |
| 5 m³/s | 5,000 L/s |
| 10 m³/s | 10,000 L/s |

| 50 m³/s | 50,000 L/s |
| 100 m³/s | 100,000 L/s |
Formula
L/s = m³/s x 1,000
Example: 1 m³/s = 1,000 L/s.

Common questions
How do I convert m³/s to L/s?
Enter the m³/s value in the converter, or multiply by the factor shown in the formula. 1 m³/s = 1,000 L/s.
What should I watch out for?
GPM and GPH use U.S. liquid gallons; imperial gallons produce a different result.
Where does this flow rate conversion come from?
Volume-per-time factors derived from NIST volume definitions and the SI second. ConverterBase uses stable definitions and fixed conversion factors, not live or rounded market data.
