About Converting Imperial gallon per Hours to Hectoliter per Hours
Imperial gallon per Hours and Hectoliter per Hours 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
hectoliter per hours = imperial gallon per hours × 0.0454609
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per hours equals 0.00000126280277778 base units, and 1 hectoliter per hours equals 0.0000277777777778 base units, so dividing one by the other gives the direct imperial gallon per hours-to-hectoliter per hours factor of 0.0454609.
Simple example
1 imp gal/h × 0.0454609 = 0.0454609 hL/h
1 imperial gallon per hours = 0.0454609 hectoliter per hours.
Real-world example
60 imp gal/h × 0.0454609 = 2.727654 hL/h
60 imperial gallon per hours = 2.727654 hectoliter per hours.

Frequently asked questions
How many hectoliter per hours are in 1 imperial gallon per hours?
1 imperial gallon per hours equals 0.0454609 hectoliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per hours to hectoliter per hours?
Multiply the imperial gallon per hours value by 0.0454609. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per hours back to imperial gallon per hours?
Use the reverse factor: 1 hectoliter per hours equals 21.99692483 imperial gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
What is a hectoliter per hours?
Hectoliter per Hours (hL/h) is a unit of flow rate.
Is the imperial gallon per hours to hectoliter per hours conversion exact?
Yes. Both imperial gallon per hours and hectoliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0454609 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.
