About Converting Hectoliter per Seconds to Imperial gallon per Seconds
Hectoliter per Seconds and Imperial gallon per Seconds 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 gallon per seconds = hectoliter per seconds × 21.9969248299
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per seconds equals 0.1 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct hectoliter per seconds-to-imperial gallon per seconds factor of 21.9969248299.
Simple example
1 hL/s × 21.99692483 = 21.99692483 imp gal/s
1 hectoliter per seconds = 21.99692483 imperial gallon per seconds.
Real-world example
60 hL/s × 21.99692483 = 1,319.81549 imp gal/s
60 hectoliter per seconds = 1,319.81549 imperial gallon per seconds.

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