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 m³/s only after allowing for the equipment tolerance and operating point.
How to convert L/s to m³/s
- Type the L/s value in the calculator.
- Keep L/s selected as the from unit and m³/s selected as the to unit.

| L/s | m³/s |
|---|---|
| 1 L/s | 0.001 m³/s |
| 10 L/s | 0.01 m³/s |
| 100 L/s | 0.1 m³/s |
| 1,000 L/s | 1 m³/s |
| 10,000 L/s | 10 m³/s |
Formula
m³/s = L/s x 0.001
Example: 1 L/s = 0.001 m³/s.

Common questions
How do I convert L/s to m³/s?
Enter the L/s value in the converter, or multiply by the factor shown in the formula. 1 L/s = 0.001 m³/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.
