About Converting Milliliter per Days to Kiloliter per Hours
Milliliter per Days and Kiloliter 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
kiloliter per hours = milliliter per days × 4.166667e-8
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 kiloliter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct milliliter per days-to-kiloliter per hours factor of 4.166667e-8.
Simple example
1 mL/d × 4.166667e-8 = 4.166667e-8 kL/h
1 milliliter per days = 4.166667e-8 kiloliter per hours.
Real-world example
60 mL/d × 4.166667e-8 = 0.0000025 kL/h
60 milliliter per days = 0.0000025 kiloliter per hours.

Frequently asked questions
How many kiloliter per hours are in 1 milliliter per days?
1 milliliter per days equals 4.166667e-8 kiloliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to kiloliter per hours?
Multiply the milliliter per days value by 4.166667e-8. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per hours back to milliliter per days?
Use the reverse factor: 1 kiloliter per hours equals 24,000,000 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 kiloliter per hours?
Kiloliter per Hours (kL/h) is a unit of flow rate.
Is the milliliter per days to kiloliter per hours conversion exact?
Yes. Both milliliter per days and kiloliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 4.166667e-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.
