About Converting Liters per Millisecond to Microliter per Seconds
Liter per Millisecond and Microliter per Seconds 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
microliter per seconds = liters per millisecond × 1000000000
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 microliter per seconds equals 1e-9 base units, so dividing one by the other gives the direct liter per millisecond-to-microliter per seconds factor of 1000000000.
Simple example
1 L/ms × 1000000000 = 1,000,000,000 uL/s
1 liter per millisecond = 1,000,000,000 microliter per seconds.
Real-world example
60 L/ms × 1000000000 = 60,000,000,000 uL/s
60 liters per millisecond = 60,000,000,000 microliter per seconds.
Conversion table
| Liter per Millisecond (L/ms) | Microliter per Seconds (uL/s) |
|---|---|
| 0.1 L/ms | 100,000,000 uL/s |
| 1 L/ms | 1,000,000,000 uL/s |
| 10 L/ms | 10,000,000,000 uL/s |
| 60 L/ms | 60,000,000,000 uL/s |
| 100 L/ms | 100,000,000,000 uL/s |
| 1,000 L/ms | 1,000,000,000,000 uL/s |
Reverse conversion: Microliter per Seconds to Liter per Millisecond
1 uL/s × 1e-9 = 1e-9 L/ms
1 microliter per seconds = 1e-9 liters per millisecond.
liters per millisecond = microliter per seconds × 1e-9

Frequently asked questions
How many microliter per seconds are in 1 liter per millisecond?
1 liter per millisecond equals 1,000,000,000 microliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to microliter per seconds?
Multiply the liter per millisecond value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert microliter per seconds back to liter per millisecond?
Use the reverse factor: 1 microliter per seconds equals 1e-9 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 microliter per seconds?
Microliter per Seconds (uL/s) is a unit of flow rate.
Is the liter per millisecond to microliter per seconds conversion exact?
Yes. Both liter per millisecond and microliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 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.
