About Converting Cup per Days to Gallon per Minutes
Cup 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 = cup per days × 0.0000434027777778
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct cup per days-to-gallon per minutes factor of 0.0000434027777778.
Simple example
1 cup/d × 0.00004340277778 = 0.0000434028 gal/min
1 cup per days = 0.0000434028 gallon per minutes.
Real-world example
60 cup/d × 0.00004340277778 = 0.0026041667 gal/min
60 cup per days = 0.0026041667 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 cup per days?
1 cup per days equals 0.0000434028 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to gallon per minutes?
Multiply the cup per days value by 0.00004340277778. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to cup per days?
Use the reverse factor: 1 gallon per minutes equals 23,040 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/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 cup per days to gallon per minutes conversion exact?
Yes. Both cup per days and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 0.00004340277778 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.
