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.
All values follow internationally accepted definitions and are rounded to the decimals you choose. The calculation runs entirely in your browser, so nothing is uploaded or stored on a server.
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.
