About Converting Hectoliter per Hours to Gallon per Days
Hectoliter per Hours and Gallon 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
gallon per days = hectoliter per hours × 634.01292566
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per hours equals 0.0000277777777778 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct hectoliter per hours-to-gallon per days factor of 634.01292566.
Simple example
1 hL/h × 634.0129257 = 634.0129257 gal/d
1 hectoliter per hours = 634.0129257 gallon per days.
Real-world example
60 hL/h × 634.0129257 = 38,040.77554 gal/d
60 hectoliter per hours = 38,040.77554 gallon per days.

Frequently asked questions
How many gallon per days are in 1 hectoliter per hours?
1 hectoliter per hours equals 634.0129257 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per hours to gallon per days?
Multiply the hectoliter per hours value by 634.0129257. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to hectoliter per hours?
Use the reverse factor: 1 gallon per days equals 0.0015772549 hectoliter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per hours?
Hectoliter per Hours (hL/h) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the hectoliter per hours to gallon per days conversion exact?
Yes. Both hectoliter per hours and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 634.0129257 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.
