About Converting Cubic Millimeter per Hours to Kiloliter per Hours
Cubic Millimeter per Hours 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 = cubic millimeter per hours × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per hours equals 2.777778e-13 base units, and 1 kiloliter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct cubic millimeter per hours-to-kiloliter per hours factor of 1e-9.
Simple example
1 mm3/h × 1e-9 = 1e-9 kL/h
1 cubic millimeter per hours = 1e-9 kiloliter per hours.
Real-world example
60 mm3/h × 1e-9 = 6e-8 kL/h
60 cubic millimeter per hours = 6e-8 kiloliter per hours.
Conversion table
| Cubic Millimeter per Hours (mm3/h) | Kiloliter per Hours (kL/h) |
|---|---|
| 0.1 mm3/h | 1e-10 kL/h |
| 1 mm3/h | 1e-9 kL/h |
| 10 mm3/h | 1e-8 kL/h |
| 60 mm3/h | 6e-8 kL/h |

Reverse conversion: Kiloliter per Hours to Cubic Millimeter per Hours
1e-9 kL/h × 1000000000 = 1 mm3/h
1e-9 kiloliter per hours = 1 cubic millimeter per hours.
cubic millimeter per hours = kiloliter per hours × 1000000000

Frequently asked questions
How many kiloliter per hours are in 1 cubic millimeter per hours?
1 cubic millimeter per hours equals 1e-9 kiloliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per hours to kiloliter per hours?
Multiply the cubic millimeter per hours value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per hours back to cubic millimeter per hours?
Use the reverse factor: 1 kiloliter per hours equals 1,000,000,000 cubic millimeter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) 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 cubic millimeter per hours to kiloliter per hours conversion exact?
Yes. Both cubic millimeter per hours and kiloliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 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.
