About Converting Cubic Meters per Millisecond to Cubic Kilometer per Days
Cubic Meter per Millisecond and Cubic Kilometer per Days 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 days = cubic meters per millisecond × 0.0864
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per millisecond equals 1000 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct cubic meter per millisecond-to-cubic kilometer per days factor of 0.0864.
Simple example
1 m3/ms × 0.0864 = 0.0864 km3/d
1 cubic meter per millisecond = 0.0864 cubic kilometer per days.
Real-world example
60 m3/ms × 0.0864 = 5.184 km3/d
60 cubic meters per millisecond = 5.184 cubic kilometer per days.

Frequently asked questions
How many cubic kilometer per days are in 1 cubic meter per millisecond?
1 cubic meter per millisecond equals 0.0864 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per millisecond to cubic kilometer per days?
Multiply the cubic meter per millisecond value by 0.0864. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to cubic meter per millisecond?
Use the reverse factor: 1 cubic kilometer per days equals 11.57407407 cubic meters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the cubic meter per millisecond to cubic kilometer per days conversion exact?
Yes. Both cubic meter per millisecond and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0864 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.
