About Converting Hectoliter per Minutes to Imperial gallons per Millisecond
Hectoliter per Minutes and Imperial gallon 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
imperial gallons per millisecond = hectoliter per minutes × 0.000366615413832
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 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct hectoliter per minutes-to-imperial gallon per millisecond factor of 0.000366615413832.
Simple example
1 hL/min × 0.0003666154138 = 0.0003666154 imp gal/ms
1 hectoliter per minutes = 0.0003666154 imperial gallons per millisecond.
Real-world example
60 hL/min × 0.0003666154138 = 0.0219969248 imp gal/ms
60 hectoliter per minutes = 0.0219969248 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 hectoliter per minutes?
1 hectoliter per minutes equals 0.0003666154 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per minutes to imperial gallon per millisecond?
Multiply the hectoliter per minutes value by 0.0003666154138. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to hectoliter per minutes?
Use the reverse factor: 1 imperial gallon per millisecond equals 2,727.654 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 imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the hectoliter per minutes to imperial gallon per millisecond conversion exact?
Yes. Both hectoliter per minutes and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0003666154138 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.
