Volumetric flow rate.
Hectoliter per Seconds to Milliliters per Millisecond Converter — hL/s to mL/ms
Convert Hectoliter per Seconds (hL/s) to Milliliter per Millisecond (mL/ms) using the exact conversion factor (1 hectoliter per seconds = 100 milliliter per millisecond). See the formula, worked examples, and conversion table.

About Converting Hectoliter per Seconds to Milliliters per Millisecond
Hectoliter per Seconds and Milliliter per Millisecond 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
milliliters per millisecond = hectoliter per seconds × 100
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 millisecond equals 0.001 base units, so dividing one by the other gives the direct hectoliter per seconds-to-milliliter per millisecond factor of 100.
Simple example
1 hL/s × 100 = 100 mL/ms
1 hectoliter per seconds = 100 milliliters per millisecond.
Real-world example
60 hL/s × 100 = 6,000 mL/ms
60 hectoliter per seconds = 6,000 milliliters per millisecond.
Conversion table
| Hectoliter per Seconds (hL/s) | Milliliter per Millisecond (mL/ms) |
|---|---|
| 0.1 hL/s | 10 mL/ms |
| 1 hL/s | 100 mL/ms |
| 10 hL/s | 1,000 mL/ms |
| 60 hL/s | 6,000 mL/ms |
| 100 hL/s | 10,000 mL/ms |
| 1,000 hL/s | 100,000 mL/ms |
Reverse conversion: Milliliter per Millisecond to Hectoliter per Seconds
100 mL/ms × 0.01 = 1 hL/s
100 milliliters per millisecond = 1 hectoliter per seconds.
hectoliter per seconds = milliliters per millisecond × 0.01

Frequently asked questions
How many milliliters per millisecond are in 1 hectoliter per seconds?
1 hectoliter per seconds equals 100 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per seconds to milliliter per millisecond?
Multiply the hectoliter per seconds value by 100. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to hectoliter per seconds?
Use the reverse factor: 1 milliliter per millisecond equals 0.01 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 millisecond?
Milliliter per Millisecond (mL/ms) is a unit of flow rate.
Is the hectoliter per seconds to milliliter per millisecond conversion exact?
Yes. Both hectoliter per seconds and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 100 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.
