Conversion method
Volume per time. Gas volumes must share the same temperature and pressure reference. US liquid and Imperial gallons are explicitly separate.
L/min = x × 60000
10 m³/s = 600000 L/min.
| m³/s | L/min |
|---|---|
| 1 | 60000 |
| 5 | 300000 |
| 10 | 600000 |
| 25 | 1500000 |
| 50 | 3000000 |

Precision of volumetric flow conversions
All 33 volumetric flow units convert through Cubic meter per second (m³/s). 33 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
