About Converting Gallon per Days to Deciliter per Seconds
Gallon per Days and Deciliter per Seconds 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 seconds = gallon per days × 0.000438126363889
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 seconds equals 0.0001 base units, so dividing one by the other gives the direct gallon per days-to-deciliter per seconds factor of 0.000438126363889.
Simple example
1 gal/d × 0.0004381263639 = 0.0004381264 dL/s
1 gallon per days = 0.0004381264 deciliter per seconds.
Real-world example
60 gal/d × 0.0004381263639 = 0.0262875818 dL/s
60 gallon per days = 0.0262875818 deciliter per seconds.

Frequently asked questions
How many deciliter per seconds are in 1 gallon per days?
1 gallon per days equals 0.0004381264 deciliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to deciliter per seconds?
Multiply the gallon per days value by 0.0004381263639. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per seconds back to gallon per days?
Use the reverse factor: 1 deciliter per seconds equals 2,282.446532 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 seconds?
Deciliter per Seconds (dL/s) is a unit of flow rate.
Is the gallon per days to deciliter per seconds conversion exact?
Yes. Both gallon per days and deciliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0004381263639 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.
