About Converting Cubic Kilometer per Seconds to Liters per Millisecond
Cubic Kilometer per Seconds and Liter 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
liters per millisecond = cubic kilometer per seconds × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per seconds equals 1000000000 base units, and 1 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct cubic kilometer per seconds-to-liter per millisecond factor of 1000000000.
Simple example
1 km3/s × 1000000000 = 1,000,000,000 L/ms
1 cubic kilometer per seconds = 1,000,000,000 liters per millisecond.
Real-world example
60 km3/s × 1000000000 = 60,000,000,000 L/ms
60 cubic kilometer per seconds = 60,000,000,000 liters per millisecond.
Conversion table
| Cubic Kilometer per Seconds (km3/s) | Liter per Millisecond (L/ms) |
|---|---|
| 0.1 km3/s | 100,000,000 L/ms |
| 1 km3/s | 1,000,000,000 L/ms |
| 10 km3/s | 10,000,000,000 L/ms |
| 60 km3/s | 60,000,000,000 L/ms |
| 100 km3/s | 100,000,000,000 L/ms |
| 1,000 km3/s | 1e+12 L/ms |
Reverse conversion: Liter per Millisecond to Cubic Kilometer per Seconds
1 L/ms × 1e-9 = 1e-9 km3/s
1 liter per millisecond = 1e-9 cubic kilometer per seconds.
cubic kilometer per seconds = liters per millisecond × 1e-9

Frequently asked questions
How many liters per millisecond are in 1 cubic kilometer per seconds?
1 cubic kilometer per seconds equals 1,000,000,000 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per seconds to liter per millisecond?
Multiply the cubic kilometer per seconds value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to cubic kilometer per seconds?
Use the reverse factor: 1 liter per millisecond equals 1e-9 cubic kilometer per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the cubic kilometer per seconds to liter per millisecond conversion exact?
Yes. Both cubic kilometer per seconds and liter per millisecond 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.
