About Converting Hectoliter per Days to Gallon per Days
Hectoliter per Days 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 days × 26.4172052358
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 days equals 4.381264e-8 base units, so dividing one by the other gives the direct hectoliter per days-to-gallon per days factor of 26.4172052358.
Simple example
1 hL/d × 26.41720524 = 26.41720524 gal/d
1 hectoliter per days = 26.41720524 gallon per days.
Real-world example
60 hL/d × 26.41720524 = 1,585.032314 gal/d
60 hectoliter per days = 1,585.032314 gallon per days.

Frequently asked questions
How many gallon per days are in 1 hectoliter per days?
1 hectoliter per days equals 26.41720524 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per days to gallon per days?
Multiply the hectoliter per days value by 26.41720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to hectoliter per days?
Use the reverse factor: 1 gallon per days equals 0.0378541178 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 days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the hectoliter per days to gallon per days conversion exact?
Yes. Both hectoliter per days and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 26.41720524 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.
