About Converting Gallon per Seconds to Gallon per Hours
Gallon 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 = gallon per seconds × 3600
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct gallon per seconds-to-gallon per hours factor of 3600.
Simple example
1 gal/s × 3600 = 3,600 gal/h
1 gallon per seconds = 3,600 gallon per hours.
Real-world example
60 gal/s × 3600 = 216,000 gal/h
60 gallon per seconds = 216,000 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 gallon per seconds?
1 gallon per seconds equals 3,600 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to gallon per hours?
Multiply the gallon per seconds value by 3600. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to gallon per seconds?
Use the reverse factor: 1 gallon per hours equals 0.0002777778 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/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 gallon per seconds to gallon per hours conversion exact?
Yes. Both gallon per seconds and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 3600 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.
