About Converting Hectoliters per Millisecond to Milliliter per Hours
Hectoliter per Millisecond and Milliliter 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
milliliter per hours = hectoliters per millisecond × 360000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per millisecond equals 100 base units, and 1 milliliter per hours equals 2.777778e-10 base units, so dividing one by the other gives the direct hectoliter per millisecond-to-milliliter per hours factor of 360000000000.
Simple example
1 hL/ms × 360000000000 = 360,000,000,000 mL/h
1 hectoliter per millisecond = 360,000,000,000 milliliter per hours.
Real-world example
60 hL/ms × 360000000000 = 2.16e+13 mL/h
60 hectoliters per millisecond = 2.16e+13 milliliter per hours.
Conversion table
| Hectoliter per Millisecond (hL/ms) | Milliliter per Hours (mL/h) |
|---|---|
| 0.1 hL/ms | 36,000,000,000 mL/h |
| 1 hL/ms | 360,000,000,000 mL/h |
| 10 hL/ms | 3.6e+12 mL/h |
| 60 hL/ms | 2.16e+13 mL/h |
| 100 hL/ms | 3.6e+13 mL/h |
| 1,000 hL/ms | 3.6e+14 mL/h |
Reverse conversion: Milliliter per Hours to Hectoliter per Millisecond
1 mL/h × 2.777778e-12 = 2.777778e-12 hL/ms
1 milliliter per hours = 2.777778e-12 hectoliters per millisecond.
hectoliters per millisecond = milliliter per hours × 2.777778e-12

Frequently asked questions
How many milliliter per hours are in 1 hectoliter per millisecond?
1 hectoliter per millisecond equals 360,000,000,000 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per millisecond to milliliter per hours?
Multiply the hectoliter per millisecond value by 360000000000. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to hectoliter per millisecond?
Use the reverse factor: 1 milliliter per hours equals 2.777778e-12 hectoliters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per millisecond?
Hectoliter per Millisecond (hL/ms) is a unit of flow rate.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
Is the hectoliter per millisecond to milliliter per hours conversion exact?
Yes. Both hectoliter per millisecond and milliliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 360000000000 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.
