Hectoliter per Seconds to Liters per Millisecond Converter — hL/s to L/ms
Convert Hectoliter per Seconds (hL/s) to Liter per Millisecond (L/ms) using the exact conversion factor (1 hectoliter per seconds = 0.1 liter per millisecond). See the formula, worked examples, and conversion table.

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

Frequently asked questions
How many liters per millisecond are in 1 hectoliter per seconds?
1 hectoliter per seconds equals 0.1 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per seconds to liter per millisecond?
Multiply the hectoliter per seconds value by 0.1. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to hectoliter per seconds?
Use the reverse factor: 1 liter per millisecond equals 10 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 liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the hectoliter per seconds to liter per millisecond conversion exact?
Yes. Both hectoliter per seconds and liter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.1 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.
