About Converting Cubic yard per Seconds to Gallon per Hours
Cubic yard per Seconds and Gallon 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
gallon per hours = cubic yard per seconds × 727106.493506
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per seconds equals 0.764554857984 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic yard per seconds-to-gallon per hours factor of 727106.493506.
Simple example
1 yd3/s × 727106.4935 = 727,106.4935 gal/h
1 cubic yard per seconds = 727,106.4935 gallon per hours.
Real-world example
60 yd3/s × 727106.4935 = 43,626,389.61 gal/h
60 cubic yard per seconds = 43,626,389.61 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 727,106.4935 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to gallon per hours?
Multiply the cubic yard per seconds value by 727106.4935. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic yard per seconds?
Use the reverse factor: 1 gallon per hours equals 0.0000013753 cubic yard per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic yard per seconds to gallon per hours conversion exact?
Yes. Both cubic yard per seconds and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 727106.4935 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.
