About Converting Liters per Millisecond to Cubic Meters per Millisecond
Liter per Millisecond and Cubic Meter per Millisecond both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
cubic meters per millisecond = liters per millisecond × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct liter per millisecond-to-cubic meter per millisecond factor of 0.001.
Simple example
1 L/ms × 0.001 = 0.001 m3/ms
1 liter per millisecond = 0.001 cubic meters per millisecond.
Real-world example
60 L/ms × 0.001 = 0.06 m3/ms
60 liters per millisecond = 0.06 cubic meters per millisecond.
Conversion table
| Liter per Millisecond (L/ms) | Cubic Meter per Millisecond (m3/ms) |
|---|---|
| 0.1 L/ms | 0.0001 m3/ms |
| 1 L/ms | 0.001 m3/ms |
| 10 L/ms | 0.01 m3/ms |
| 60 L/ms | 0.06 m3/ms |
| 100 L/ms | 0.1 m3/ms |
| 1,000 L/ms | 1 m3/ms |
Reverse conversion: Cubic Meter per Millisecond to Liter per Millisecond
0.001 m3/ms × 1000 = 1 L/ms
0.001 cubic meters per millisecond = 1 liter per millisecond.
liters per millisecond = cubic meters per millisecond × 1000

Frequently asked questions
How many cubic meters per millisecond are in 1 liter per millisecond?
1 liter per millisecond equals 0.001 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to cubic meter per millisecond?
Multiply the liter per millisecond value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per millisecond back to liter per millisecond?
Use the reverse factor: 1 cubic meter per millisecond equals 1,000 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
Is the liter per millisecond to cubic meter per millisecond conversion exact?
Yes. Both liter per millisecond and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
