About Cubic meter per hour (m³/hr)

A metric flow-rate unit equal to 1/3,600 m³/s. m³/hr is the standard unit for industrial process flows, HVAC air handling, pump sizing in European specifications, natural-gas metering, and municipal water treatment capacity. European building-code air-exchange requirements and pump curves are almost always expressed in m³/hr.

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.
