About Converting Milliliter per Days to Cubic Kilometer per Days
Milliliter per Days 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 = milliliter per days × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per days equals 1.157407e-11 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct milliliter per days-to-cubic kilometer per days factor of 1e-15.
Simple example
1 mL/d × 1e-15 = 1e-15 km3/d
1 milliliter per days = 1e-15 cubic kilometer per days.
Real-world example
60 mL/d × 1e-15 = 6e-14 km3/d
60 milliliter per days = 6e-14 cubic kilometer per days.

Reverse conversion: Cubic Kilometer per Days to Milliliter per Days
1e-15 km3/d × 1e+15 = 1 mL/d
1e-15 cubic kilometer per days = 1 milliliter per days.
milliliter per days = cubic kilometer per days × 1e+15

Frequently asked questions
How many cubic kilometer per days are in 1 milliliter per days?
1 milliliter per days equals 1e-15 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to cubic kilometer per days?
Multiply the milliliter per days value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to milliliter per days?
Use the reverse factor: 1 cubic kilometer per days equals 1e+15 milliliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per days?
Milliliter per Days (mL/d) 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 milliliter per days to cubic kilometer per days conversion exact?
Yes. Both milliliter per days and cubic kilometer per days 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.
