GPM to GPH Calculator

Flow Rate Conversion Relationship

The flow rate in gallons per hour (GPH) can be converted from gallons per minute (GPM) using the following formula:

GPH = GPM × 60

Flow Rate Input:

Flow rate measures the volume of fluid passing through a point per unit time. Common units include:

  • GPM (Gallons per Minute): Standard in the US for water flow.
  • GPH (Gallons per Hour): Used for slower flows.
  • GPD (Gallons per Day): Common in daily water usage.
  • L/min (Liters per Minute): Metric unit for medium flows.
  • L/s (Liters per Second): Metric unit for high flows.
  • L/h (Liters per Hour): Metric unit for low flows.
  • m³/h (Cubic Meters per Hour): Used in industrial settings.
  • m³/s (Cubic Meters per Second): Standard metric unit for large flows.
  • CFM (Cubic Feet per Minute): Common in HVAC systems.

Practical Applications

This converter is useful in various scenarios:

  • Water Pumps: Convert GPM to GPH for hourly usage tracking.
  • Irrigation Systems: Adjust flow rates for sprinkler planning.
  • Household Use: Estimate water flow in slower-rate appliances.

Example Calculation

If the flow rate is 10 GPM, the conversion to GPH would be:

GPH = 10 × 60 = 600 GPH

Similarly:

  • GPD = 600 × 24 ≈ 14400 GPD
  • L/min = 600 / 15.850323141 ≈ 37.854 L/min
  • L/s = 600 / 951.0193885 ≈ 0.631 L/s
  • m³/h = 600 / 264.172052 ≈ 2.271 m³/h
  • CFM = 600 / 448.8311694 ≈ 1.337 CFM

Conversion Constants

Key conversion factors:

  • 1 Gallon = 3.785411784 Liters
  • 1 m³ = 1000 Liters
  • 1 ft³ = 7.48051948 Gallons
  • 1 minute = 60 seconds
  • 1 hour = 3600 seconds
  • 1 day = 24 hours
