Flow rate conversion is critical in hydraulic engineering, water supply, and medical infusion devices. Large-scale water diversion projects use cubic meters per second. Household faucets and showerheads use liters per minute. In industrial HVAC, gallons per minute (GPM) are core parameters.
History & Background
Flow measurement technology developed alongside urban water supply systems. Ancient Romans estimated water supply by measuring channel cross-sections and flow velocity. After the Industrial Revolution, the Venturi meter and orifice plate were invented.
Conversion Details
Flow rate conversion is based on liters per second (L/s).
Common conversions: 1 m³/h ≈ 16.67 L/min, 1 US gpm ≈ 3.785 L/min, 1 cfm ≈ 0.472 L/s.
