About Converting Hectoliter per Hours to Gallon per Minutes
Hectoliter per Hours and Gallon per Minutes 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
gallon per minutes = hectoliter per hours × 0.44028675393
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per hours equals 0.0000277777777778 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct hectoliter per hours-to-gallon per minutes factor of 0.44028675393.
Simple example
1 hL/h × 0.4402867539 = 0.4402867539 gal/min
1 hectoliter per hours = 0.4402867539 gallon per minutes.
Real-world example
60 hL/h × 0.4402867539 = 26.41720524 gal/min
60 hectoliter per hours = 26.41720524 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 hectoliter per hours?
1 hectoliter per hours equals 0.4402867539 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per hours to gallon per minutes?
Multiply the hectoliter per hours value by 0.4402867539. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to hectoliter per hours?
Use the reverse factor: 1 gallon per minutes equals 2.27124707 hectoliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per hours?
Hectoliter per Hours (hL/h) is a unit of flow rate.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the hectoliter per hours to gallon per minutes conversion exact?
Yes. Both hectoliter per hours and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.4402867539 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.
