Flow Rate Converter

Convert between all common volumetric flow rate units including liters per minute, US gallons per minute (GPM), cubic feet per minute (CFM), and cubic meters per hour. Essential for plumbing, HVAC, and fluid dynamics.

Flow rate measures the volume of fluid passing a point per unit time. It is critical in plumbing, HVAC, hydraulics, and process engineering.

Key Conversion Factors:

  • 1 L/min = 0.2642 US GPM
  • 1 US GPM = 3.7854 L/min
  • 1 CFM = 28.317 L/min
  • 1 m³/h = 16.667 L/min
  • 1 m³/h = 4.403 US GPM
  • 1 CFS = 448.8 US GPM

Common Flow Rates:

  • Kitchen faucet: 8-9 L/min (2.0-2.2 GPM)
  • Shower head: 7.6-9.5 L/min (2.0-2.5 GPM)
  • Garden hose: 23-38 L/min (6-10 GPM)
  • Fire hydrant: 950-5,700 L/min (250-1,500 GPM)
