About Liter per minute (L/min)

A metric flow-rate unit commonly used for household appliances, medical devices (IV pumps, ventilators), dispensing equipment, and small-flow industrial processes. A shower head in a metric country is typically 8–12 L/min; a garden hose is 10–30 L/min. L/min is the default unit for oxygen delivery in medicine (nasal cannula at 1–5 L/min).

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.
