Hectoliter per Seconds to Hectoliters per Millisecond Converter — hL/s to hL/ms
Convert Hectoliter per Seconds (hL/s) to Hectoliter per Millisecond (hL/ms) using the exact conversion factor (1 hectoliter per seconds = 0.001 hectoliter per millisecond). See the formula, worked examples, and conversion table.

About Converting Hectoliter per Seconds to Hectoliters per Millisecond
Hectoliter per Seconds and Hectoliter 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
hectoliters per millisecond = hectoliter per seconds × 0.001
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 hectoliter per millisecond equals 100 base units, so dividing one by the other gives the direct hectoliter per seconds-to-hectoliter per millisecond factor of 0.001.
Simple example
1 hL/s × 0.001 = 0.001 hL/ms
1 hectoliter per seconds = 0.001 hectoliters per millisecond.
Real-world example
60 hL/s × 0.001 = 0.06 hL/ms
60 hectoliter per seconds = 0.06 hectoliters per millisecond.
Conversion table
| Hectoliter per Seconds (hL/s) | Hectoliter per Millisecond (hL/ms) |
|---|---|
| 0.1 hL/s | 0.0001 hL/ms |
| 1 hL/s | 0.001 hL/ms |
| 10 hL/s | 0.01 hL/ms |
| 60 hL/s | 0.06 hL/ms |
| 100 hL/s | 0.1 hL/ms |
| 1,000 hL/s | 1 hL/ms |
Reverse conversion: Hectoliter per Millisecond to Hectoliter per Seconds
0.001 hL/ms × 1000 = 1 hL/s
0.001 hectoliters per millisecond = 1 hectoliter per seconds.
hectoliter per seconds = hectoliters per millisecond × 1000

Frequently asked questions
How many hectoliters per millisecond are in 1 hectoliter per seconds?
1 hectoliter per seconds equals 0.001 hectoliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per seconds to hectoliter per millisecond?
Multiply the hectoliter per seconds value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per millisecond back to hectoliter per seconds?
Use the reverse factor: 1 hectoliter per millisecond equals 1,000 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 hectoliter per millisecond?
Hectoliter per Millisecond (hL/ms) is a unit of flow rate.
Is the hectoliter per seconds to hectoliter per millisecond conversion exact?
Yes. Both hectoliter per seconds and hectoliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
