About Converting Gallon per Minutes to Deciliter per Hours
Gallon per Minutes and Deciliter 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
deciliter per hours = gallon per minutes × 2271.2470704
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 hours equals 2.777778e-8 base units, so dividing one by the other gives the direct gallon per minutes-to-deciliter per hours factor of 2271.2470704.
Simple example
1 gal/min × 2271.24707 = 2,271.24707 dL/h
1 gallon per minutes = 2,271.24707 deciliter per hours.
Real-world example
60 gal/min × 2271.24707 = 136,274.8242 dL/h
60 gallon per minutes = 136,274.8242 deciliter per hours.
Conversion table
| Gallon per Minutes (gal/min) | Deciliter per Hours (dL/h) |

Reverse conversion: Deciliter per Hours to Gallon per Minutes
1 dL/h × 0.0004402867539 = 0.0004402868 gal/min
1 deciliter per hours = 0.0004402868 gallon per minutes.
gallon per minutes = deciliter per hours × 0.00044028675393

Frequently asked questions
How many deciliter per hours are in 1 gallon per minutes?
1 gallon per minutes equals 2,271.24707 deciliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per minutes to deciliter per hours?
Multiply the gallon per minutes value by 2271.24707. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per hours back to gallon per minutes?
Use the reverse factor: 1 deciliter per hours equals 0.0004402868 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 hours?
Deciliter per Hours (dL/h) is a unit of flow rate.
Is the gallon per minutes to deciliter per hours conversion exact?
Yes. Both gallon per minutes and deciliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 2271.24707 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.
