About Converting Cubic Meter per Days to Gallon per Days
Cubic Meter per Days and Gallon 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. Both are volumetric flow rate units.
Formula
gallon per days = cubic meter per days × 264.172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per days equals 0.0000115740740741 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct cubic meter per days-to-gallon per days factor of 264.172052358.
Simple example
1 m3/d × 264.1720524 = 264.1720524 gal/d
1 cubic meter per days = 264.1720524 gallon per days.
Real-world example
60 m3/d × 264.1720524 = 15,850.32314 gal/d
60 cubic meter per days = 15,850.32314 gallon per days.

Frequently asked questions
How many gallon per days are in 1 cubic meter per days?
1 cubic meter per days equals 264.1720524 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per days to gallon per days?
Multiply the cubic meter per days value by 264.1720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to cubic meter per days?
Use the reverse factor: 1 gallon per days equals 0.0037854118 cubic meter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the cubic meter per days to gallon per days conversion exact?
Yes. Both cubic meter per days and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 264.1720524 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.
