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.

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.

Understanding Liters per second

The Liter per second (symbol: L/s) is a unit of volumetric flow rate. 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.

It belongs to the metric measurement system.

Liters per second are commonly used in plumbing, HVAC systems, and chemical process engineering.

Understanding Cubic feet per minute

The Cubic foot per minute (symbol: CFM) is a unit of volumetric flow rate. 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.

It belongs to the imperial measurement system.

Cubic feet per minute are commonly used in plumbing, HVAC systems, and chemical process engineering.

Why Convert Liters per second to Cubic feet per minute?
