gph stands for Gallons per hour, an engineering unit abbreviation.
Flow rate in US gallons per hour, used for the fuel burn of boats, generators and aircraft, aquarium and pond pumps, and drip irrigation. Drip emitters typically deliver 0.5 to 2 gph.
Example: The generator burns about 0.75 gph at half load.
Usage notes
Pilots plan fuel by gph: a Cessna 172 burns roughly 8 to 9 gph in cruise. Boaters combine gph with speed to estimate range. Aquarium pumps are sized to turn the tank volume over several times per hour.
