About Converting Quart per Days to Gallon per Minutes
Quart per Days and Gallon per Minutes 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
gallon per minutes = quart per days × 0.000173611111111
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct quart per days-to-gallon per minutes factor of 0.000173611111111.
Simple example
1 qt/d × 0.0001736111111 = 0.0001736111 gal/min
1 quart per days = 0.0001736111 gallon per minutes.
Real-world example
60 qt/d × 0.0001736111111 = 0.0104166667 gal/min
60 quart per days = 0.0104166667 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 quart per days?
1 quart per days equals 0.0001736111 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to gallon per minutes?
Multiply the quart per days value by 0.0001736111111. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to quart per days?
Use the reverse factor: 1 gallon per minutes equals 5,760 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
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.
Is the quart per days to gallon per minutes conversion exact?
Yes. Both quart per days and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.0001736111111 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.
