About Converting Hectoliter per Seconds to Milliliter per Hours
Hectoliter per Seconds 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 = hectoliter per seconds × 360000000
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per seconds equals 0.1 base units, and 1 milliliter per hours equals 2.777778e-10 base units, so dividing one by the other gives the direct hectoliter per seconds-to-milliliter per hours factor of 360000000.
Simple example
1 hL/s × 360000000 = 360,000,000 mL/h
1 hectoliter per seconds = 360,000,000 milliliter per hours.
Real-world example
60 hL/s × 360000000 = 21,600,000,000 mL/h
60 hectoliter per seconds = 21,600,000,000 milliliter per hours.
Conversion table
| Hectoliter per Seconds (hL/s) | Milliliter per Hours (mL/h) |
|---|---|
| 0.1 hL/s | 36,000,000 mL/h |
| 1 hL/s | 360,000,000 mL/h |
| 10 hL/s | 3,600,000,000 mL/h |
| 60 hL/s | 21,600,000,000 mL/h |
| 100 hL/s | 36,000,000,000 mL/h |
| 1,000 hL/s | 360,000,000,000 mL/h |
Reverse conversion: Milliliter per Hours to Hectoliter per Seconds
1 mL/h × 2.777778e-9 = 2.777778e-9 hL/s
1 milliliter per hours = 2.777778e-9 hectoliter per seconds.
hectoliter per seconds = milliliter per hours × 2.777778e-9

Frequently asked questions
How many milliliter per hours are in 1 hectoliter per seconds?
1 hectoliter per seconds equals 360,000,000 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per seconds to milliliter per hours?
Multiply the hectoliter per seconds value by 360000000. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to hectoliter per seconds?
Use the reverse factor: 1 milliliter per hours equals 2.777778e-9 hectoliter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per seconds?
Hectoliter per Seconds (hL/s) 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 seconds to milliliter per hours conversion exact?
Yes. Both hectoliter per seconds and milliliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 360000000 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.
