About Converting Hectoliter per Days to Gallon per Hours
Hectoliter per Days and Gallon 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
gallon per hours = hectoliter per days × 1.10071688483
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per days equals 0.00000115740740741 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct hectoliter per days-to-gallon per hours factor of 1.10071688483.
Simple example
1 hL/d × 1.100716885 = 1.100716885 gal/h
1 hectoliter per days = 1.100716885 gallon per hours.
Real-world example
60 hL/d × 1.100716885 = 66.04301309 gal/h
60 hectoliter per days = 66.04301309 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 hectoliter per days?
1 hectoliter per days equals 1.100716885 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to gallon per hours?
Multiply the hectoliter per days value by 1.100716885. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to hectoliter per days?
Use the reverse factor: 1 gallon per hours equals 0.9084988282 hectoliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per days?
Hectoliter per Days (hL/d) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the hectoliter per days to gallon per hours conversion exact?
Yes. Both hectoliter per days and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.100716885 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.
