About Converting Hectoliter per Minutes to Gallons per Millisecond
Hectoliter per Minutes and 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
gallons per millisecond = hectoliter per minutes × 0.00044028675393
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 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct hectoliter per minutes-to-gallon per millisecond factor of 0.00044028675393.
Simple example
1 hL/min × 0.0004402867539 = 0.0004402868 gal/ms
1 hectoliter per minutes = 0.0004402868 gallons per millisecond.
Real-world example
60 hL/min × 0.0004402867539 = 0.0264172052 gal/ms
60 hectoliter per minutes = 0.0264172052 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 hectoliter per minutes?
1 hectoliter per minutes equals 0.0004402868 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per minutes to gallon per millisecond?
Multiply the hectoliter per minutes value by 0.0004402867539. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to hectoliter per minutes?
Use the reverse factor: 1 gallon per millisecond equals 2,271.24707 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 gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the hectoliter per minutes to gallon per millisecond conversion exact?
Yes. Both hectoliter per minutes and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0004402867539 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.
