About Converting Gallon per Seconds to Hectoliter per Days
Gallon per Seconds 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 = gallon per seconds × 3270.59578138
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 days equals 0.00000115740740741 base units, so dividing one by the other gives the direct gallon per seconds-to-hectoliter per days factor of 3270.59578138.
Simple example
1 gal/s × 3270.595781 = 3,270.595781 hL/d
1 gallon per seconds = 3,270.595781 hectoliter per days.
Real-world example
60 gal/s × 3270.595781 = 196,235.7469 hL/d
60 gallon per seconds = 196,235.7469 hectoliter per days.

Frequently asked questions
How many hectoliter per days are in 1 gallon per seconds?
1 gallon per seconds equals 3,270.595781 hectoliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to hectoliter per days?
Multiply the gallon per seconds value by 3270.595781. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per days back to gallon per seconds?
Use the reverse factor: 1 hectoliter per days equals 0.0003057547 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 days?
Hectoliter per Days (hL/d) is a unit of flow rate.
Is the gallon per seconds to hectoliter per days conversion exact?
Yes. Both gallon per seconds and hectoliter per days are defined by fixed standards rather than physical artifacts, so the factor of 3270.595781 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.
