About Gallon per hour (GPH)
A US flow-rate unit (US gallons per hour) used for slow, metered, or steady-state low-flow applications. Common applications: aquarium and pond circulation pumps (a typical canister filter for a 75-gallon aquarium delivers 250-350 GPH), water-feature and fountain recirculators, agricultural drip-irrigation emitters (rated 0.5-4 GPH at design pressure per ASABE EP458), residential oil-burner fuel nozzle ratings (most US oil furnaces use 0.5-2.0 GPH nozzles), commercial fuel-dispensing meters (where GPH is the throughput rating, often combined with a separate gallons-pumped-per-minute peak), and reverse-osmosis water-purification membranes (GPH membrane capacity is the marketing spec on most US residential RO systems). Marine fuel-flow meters typically report consumption in GPH, a useful figure for cruising range and fuel-burn-per-mile calculations. 1 GPH = 0.01667 GPM = 0.0631 L/min = 1.0515 × 10⁻⁶ m³/s.
About Cubic meter per hour (m³/hr)
A metric flow-rate unit equal to exactly 1/3,600 m³/s. m³/hr is the de-facto standard unit for industrial process flows in metric countries, HVAC air handling (DIN EN 16798 / ASHRAE 62.1 ventilation calcs), pump sizing in European pump curves (KSB, Grundfos, Wilo specifications), natural-gas metering and the gas grid balance reports (TSO data is in Mm³/hr), municipal water-treatment plant capacity, and biogas/anaerobic-digester output. European building-code minimum air-exchange rates (e.g., German DIN 1946 fresh-air requirements per occupant) and Eurovent-certified fan-coil ratings are almost always expressed in m³/hr. Practical reference: a typical residential heat-recovery ventilation unit moves 100-400 m³/hr; an industrial centrifugal pump might be rated at 50-5,000 m³/hr. Convert to GPM by multiplying by 4.403, to CFM by multiplying by 0.5886, to L/s by dividing by 3.6.
