About Converting Gallon per Minutes to Quart per Decades
Gallon per Minutes and Quart per Decades 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
quart per decades = gallon per minutes × 21037968
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 quart per decades equals 2.998873e-12 base units, so dividing one by the other gives the direct gallon per minutes-to-quart per decades factor of 21037968.
Simple example
1 gal/min × 21037968 = 21,037,968 qt/decade
1 gallon per minutes = 21,037,968 quart per decades.
Real-world example
60 gal/min × 21037968 = 1,262,278,080 qt/decade
60 gallon per minutes = 1,262,278,080 quart per decades.

How do I convert quart per decades back to gallon per minutes?
Use the reverse factor: 1 quart per decades equals 4.753311e-8 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 quart per decades?
Quart per Decades (qt/decade) is a unit of flow rate.
Is the gallon per minutes to quart per decades conversion exact?
Yes. Both gallon per minutes and quart per decades are defined by fixed standards rather than physical artifacts, so the factor of 21037968 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.
