About Converting Imperial gallon per Days to Hectoliter per Days
Imperial gallon per Days and Hectoliter per Days 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 days = imperial gallon per days × 0.0454609
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 hectoliter per days equals 0.00000115740740741 base units, so dividing one by the other gives the direct imperial gallon per days-to-hectoliter per days factor of 0.0454609.
Simple example
1 imp gal/d × 0.0454609 = 0.0454609 hL/d
1 imperial gallon per days = 0.0454609 hectoliter per days.
Real-world example
60 imp gal/d × 0.0454609 = 2.727654 hL/d
60 imperial gallon per days = 2.727654 hectoliter per days.

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