About Converting Gallon per Days to Cubic yard per Hours
Gallon per Days and Cubic yard per Hours 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
cubic yard per hours = gallon per days × 0.000206297153635
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 cubic yard per hours equals 0.00021237634944 base units, so dividing one by the other gives the direct gallon per days-to-cubic yard per hours factor of 0.000206297153635.
Simple example
1 gal/d × 0.0002062971536 = 0.0002062972 yd3/h
1 gallon per days = 0.0002062972 cubic yard per hours.
Real-world example
60 gal/d × 0.0002062971536 = 0.0123778292 yd3/h
60 gallon per days = 0.0123778292 cubic yard per hours.

How do I convert cubic yard per hours back to gallon per days?
Use the reverse factor: 1 cubic yard per hours equals 4,847.376623 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a cubic yard per hours?
Cubic yard per Hours (yd3/h) is a unit of flow rate.
Is the gallon per days to cubic yard per hours conversion exact?
Yes. Both gallon per days and cubic yard per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0002062971536 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.
