About Converting Microliter per Seconds to Cubic Kilometer per Seconds
Microliter per Seconds and Cubic Kilometer 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
cubic kilometer per seconds = microliter per seconds × 1e-18
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per seconds equals 1e-9 base units, and 1 cubic kilometer per seconds equals 1000000000 base units, so dividing one by the other gives the direct microliter per seconds-to-cubic kilometer per seconds factor of 1e-18.
Simple example
1 uL/s × 1e-18 = 1e-18 km3/s
1 microliter per seconds = 1e-18 cubic kilometer per seconds.
Real-world example
60 uL/s × 1e-18 = 6e-17 km3/s
60 microliter per seconds = 6e-17 cubic kilometer per seconds.

Reverse conversion: Cubic Kilometer per Seconds to Microliter per Seconds
1e-18 km3/s × 1e+18 = 1 uL/s
1e-18 cubic kilometer per seconds = 1 microliter per seconds.
microliter per seconds = cubic kilometer per seconds × 1e+18

Frequently asked questions
How many cubic kilometer per seconds are in 1 microliter per seconds?
1 microliter per seconds equals 1e-18 cubic kilometer per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per seconds to cubic kilometer per seconds?
Multiply the microliter per seconds value by 1e-18. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per seconds back to microliter per seconds?
Use the reverse factor: 1 cubic kilometer per seconds equals 1e+18 microliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a microliter per seconds?
Microliter per Seconds (uL/s) is a unit of flow rate.
What is a cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
Is the microliter per seconds to cubic kilometer per seconds conversion exact?
Yes. Both microliter per seconds and cubic kilometer per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1e-18 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.
