About Converting Gallon per Minutes to Deciliter per Seconds
Gallon per Minutes 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
deciliter per seconds = gallon per minutes × 0.630901964
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 deciliter per seconds equals 0.0001 base units, so dividing one by the other gives the direct gallon per minutes-to-deciliter per seconds factor of 0.630901964.
Simple example
1 gal/min × 0.630901964 = 0.630901964 dL/s
1 gallon per minutes = 0.630901964 deciliter per seconds.
Real-world example
60 gal/min × 0.630901964 = 37.85411784 dL/s
60 gallon per minutes = 37.85411784 deciliter per seconds.

Frequently asked questions
How many deciliter per seconds are in 1 gallon per minutes?
1 gallon per minutes equals 0.630901964 deciliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to deciliter per seconds?
Multiply the gallon per minutes value by 0.630901964. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per seconds back to gallon per minutes?
Use the reverse factor: 1 deciliter per seconds equals 1.585032314 gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a deciliter per seconds?
Deciliter per Seconds (dL/s) is a unit of flow rate.
Is the gallon per minutes to deciliter per seconds conversion exact?
Yes. Both gallon per minutes and deciliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.630901964 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
