About Converting Cubic Kilometer per Hours to Cubic Centimeters per Millisecond
Cubic Kilometer per Hours and Cubic Centimeter 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 centimeters per millisecond = cubic kilometer per hours × 277777777.778
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per hours equals 277777.777778 base units, and 1 cubic centimeter per millisecond equals 0.001 base units, so dividing one by the other gives the direct cubic kilometer per hours-to-cubic centimeter per millisecond factor of 277777777.778.
Simple example
1 km3/h × 277777777.8 = 277,777,777.8 cm3/ms
1 cubic kilometer per hours = 277,777,777.8 cubic centimeters per millisecond.
Real-world example
60 km3/h × 277777777.8 = 16,666,666,670 cm3/ms
60 cubic kilometer per hours = 16,666,666,670 cubic centimeters per millisecond.

Frequently asked questions
How many cubic centimeters per millisecond are in 1 cubic kilometer per hours?
1 cubic kilometer per hours equals 277,777,777.8 cubic centimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per hours to cubic centimeter per millisecond?
Multiply the cubic kilometer per hours value by 277777777.8. The converter above does this instantly to whatever precision you set.
How do I convert cubic centimeter per millisecond back to cubic kilometer per hours?
Use the reverse factor: 1 cubic centimeter per millisecond equals 3.6e-9 cubic kilometer per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per hours?
Cubic Kilometer per Hours (km3/h) is a unit of flow rate.
What is a cubic centimeter per millisecond?
Cubic Centimeter per Millisecond (cm3/ms) is a unit of flow rate.
Is the cubic kilometer per hours to cubic centimeter per millisecond conversion exact?
Yes. Both cubic kilometer per hours and cubic centimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 277777777.8 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.
