About Gallon per hour (GPH)
A US flow-rate unit for slow/metered flows. Used on aquarium pumps, water-feature recirculators, irrigation drip emitters, oil burners, fuel-dispensing meters, and some industrial dosing equipment. Boat fuel-flow meters also report fuel consumption in GPH, a useful figure for cruising range calculations.
About Cubic meter per second (m³/s)
The SI unit of volumetric flow rate — the volume of fluid passing a given point per unit time. m³/s is the universal unit in fluid-dynamics research, large-pipeline engineering, river and flood hydrology, and industrial process flow. Also called the "cumec" in hydrology. The Amazon River discharge is ~209,000 m³/s. Most practical applications use smaller units like L/s or m³/hr because m³/s values are typically very small (a household faucet is ~0.0002 m³/s).
