About Converting Gallon per Minutes to Cubic Meter per Days
Gallon per Minutes and Cubic Meter per Days 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
cubic meter per days = gallon per minutes × 5.45099296896
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 cubic meter per days equals 0.0000115740740741 base units, so dividing one by the other gives the direct gallon per minutes-to-cubic meter per days factor of 5.45099296896.
Simple example
1 gal/min × 5.450992969 = 5.450992969 m3/d
1 gallon per minutes = 5.450992969 cubic meter per days.
Real-world example
60 gal/min × 5.450992969 = 327.0595781 m3/d
60 gallon per minutes = 327.0595781 cubic meter per days.

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 cubic meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
Is the gallon per minutes to cubic meter per days conversion exact?
Yes. Both gallon per minutes and cubic meter per days are defined by fixed standards rather than physical artifacts, so the factor of 5.450992969 used above is exact to as many digits as you choose to display.

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.
