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 minute (GPM)
A US customary flow-rate unit (US gallons per minute) used in plumbing, HVAC, fire protection, and swimming-pool circulation. GPM is the primary US sizing unit for residential water softeners, well pumps, sprinkler systems, and NFPA-standard fire-protection systems. A typical US showerhead is 2–2.5 GPM; a 4-inch fire hydrant can deliver 500–1,500 GPM. 1 GPM ≈ 3.785 L/min.
