About Converting Gallon per Seconds to Hectoliter per Hours
Gallon per Seconds 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 = gallon per seconds × 136.274824224
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 hectoliter per hours equals 0.0000277777777778 base units, so dividing one by the other gives the direct gallon per seconds-to-hectoliter per hours factor of 136.274824224.
Simple example
1 gal/s × 136.2748242 = 136.2748242 hL/h
1 gallon per seconds = 136.2748242 hectoliter per hours.
Real-world example
60 gal/s × 136.2748242 = 8,176.489453 hL/h
60 gallon per seconds = 8,176.489453 hectoliter per hours.

Frequently asked questions
How many hectoliter per hours are in 1 gallon per seconds?
1 gallon per seconds equals 136.2748242 hectoliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to hectoliter per hours?
Multiply the gallon per seconds value by 136.2748242. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per hours back to gallon per seconds?
Use the reverse factor: 1 hectoliter per hours equals 0.0073381126 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) 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 gallon per seconds to hectoliter per hours conversion exact?
Yes. Both gallon per seconds and hectoliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 136.2748242 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.
