About Cubic foot per minute (CFM)
An imperial flow-rate unit dominant in US HVAC — air-handler capacity, duct sizing, bathroom/kitchen exhaust fan ratings, compressed-air-system sizing, and dust collection. A residential bathroom fan is typically 50–110 CFM; a central-AC air handler for a 2,000 ft² home delivers 800–1,200 CFM. Converting CFM to m³/hr (×1.699) is common for international HVAC equipment.
About Liter per second (L/s)
A metric flow-rate unit equal to 0.001 m³/s. L/s is the typical unit for plumbing fixtures in metric-using countries, fire-pump capacities, and medium-flow industrial processes. A typical kitchen faucet is 0.1–0.15 L/s; a fire hydrant can deliver 30–60 L/s. Converting L/s to GPM (×15.85) is routine for international pump and plumbing equipment.
