About Converting Gallon per Days to Deciliter per Days
Gallon per Days and Deciliter 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
deciliter per days = gallon per days × 37.85411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 deciliter per days equals 1.157407e-9 base units, so dividing one by the other gives the direct gallon per days-to-deciliter per days factor of 37.85411784.
Simple example
1 gal/d × 37.85411784 = 37.85411784 dL/d
1 gallon per days = 37.85411784 deciliter per days.
Real-world example
60 gal/d × 37.85411784 = 2,271.24707 dL/d
60 gallon per days = 2,271.24707 deciliter per days.

Frequently asked questions
How many deciliter per days are in 1 gallon per days?
1 gallon per days equals 37.85411784 deciliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to deciliter per days?
Multiply the gallon per days value by 37.85411784. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per days back to gallon per days?
Use the reverse factor: 1 deciliter per days equals 0.0264172052 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a deciliter per days?
Deciliter per Days (dL/d) is a unit of flow rate.
Is the gallon per days to deciliter per days conversion exact?
Yes. Both gallon per days and deciliter per days are defined by fixed standards rather than physical artifacts, so the factor of 37.85411784 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.
