About Converting Hectoliter per Minutes to Milliliters per Millisecond
Hectoliter per Minutes 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 minutes × 1.66666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per minutes equals 0.00166666666667 base units, and 1 milliliter per millisecond equals 0.001 base units, so dividing one by the other gives the direct hectoliter per minutes-to-milliliter per millisecond factor of 1.66666666667.
Simple example
1 hL/min × 1.666666667 = 1.666666667 mL/ms
1 hectoliter per minutes = 1.666666667 milliliters per millisecond.
Real-world example
60 hL/min × 1.666666667 = 100 mL/ms
60 hectoliter per minutes = 100 milliliters per millisecond.
Conversion table
| Hectoliter per Minutes (hL/min) | Milliliter per Millisecond (mL/ms) |

Reverse conversion: Milliliter per Millisecond to Hectoliter per Minutes
1.666666667 mL/ms × 0.6 = 1 hL/min
1.666666667 milliliters per millisecond = 1 hectoliter per minutes.
hectoliter per minutes = milliliters per millisecond × 0.6

Frequently asked questions
How many milliliters per millisecond are in 1 hectoliter per minutes?
1 hectoliter per minutes equals 1.666666667 milliliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per minutes to milliliter per millisecond?
Multiply the hectoliter per minutes value by 1.666666667. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per millisecond back to hectoliter per minutes?
Use the reverse factor: 1 milliliter per millisecond equals 0.6 hectoliter per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per minutes?
Hectoliter per Minutes (hL/min) 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 minutes to milliliter per millisecond conversion exact?
Yes. Both hectoliter per minutes and milliliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.666666667 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.
