About Converting Milliliter per Hours to Cubic Kilometer per Hours
Milliliter per Hours and Cubic Kilometer per Hours 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 hours = milliliter per hours × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per hours equals 2.777778e-10 base units, and 1 cubic kilometer per hours equals 277777.777778 base units, so dividing one by the other gives the direct milliliter per hours-to-cubic kilometer per hours factor of 1e-15.
Simple example
1 mL/h × 1e-15 = 1e-15 km3/h
1 milliliter per hours = 1e-15 cubic kilometer per hours.
Real-world example
60 mL/h × 1e-15 = 6e-14 km3/h
60 milliliter per hours = 6e-14 cubic kilometer per hours.

Reverse conversion: Cubic Kilometer per Hours to Milliliter per Hours
1e-15 km3/h × 1e+15 = 1 mL/h
1e-15 cubic kilometer per hours = 1 milliliter per hours.
milliliter per hours = cubic kilometer per hours × 1e+15

Frequently asked questions
How many cubic kilometer per hours are in 1 milliliter per hours?
1 milliliter per hours equals 1e-15 cubic kilometer per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per hours to cubic kilometer per hours?
Multiply the milliliter per hours value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per hours back to milliliter per hours?
Use the reverse factor: 1 cubic kilometer per hours equals 1e+15 milliliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
What is a cubic kilometer per hours?
Cubic Kilometer per Hours (km3/h) is a unit of flow rate.
Is the milliliter per hours to cubic kilometer per hours conversion exact?
Yes. Both milliliter per hours and cubic kilometer per hours are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 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.
