GPM to GPH Formula:
| From: | To: |
GPM to GPH conversion is a simple calculation that converts flow rate from gallons per minute to gallons per hour. This conversion is commonly used in fluid dynamics, plumbing, irrigation systems, and industrial applications where flow rates need to be compared or scaled over different time periods.
The calculator uses the conversion formula:
Where:
Explanation: Since there are 60 minutes in one hour, multiplying gallons per minute by 60 gives the equivalent flow rate in gallons per hour.
Details: Converting between different time units for flow rates is essential for system design, capacity planning, and comparing performance metrics across different time scales. GPH is often used for longer-term flow analysis while GPM is more common for real-time monitoring.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will instantly convert it to gallons per hour (GPH).
Q1: Why convert GPM to GPH?
A: GPH provides a better understanding of total volume over longer periods, useful for calculating daily water usage, chemical dosing rates, or system capacity requirements.
Q2: What are typical GPM values for household applications?
A: Standard shower: 2.0-2.5 GPM, kitchen faucet: 1.5-2.2 GPM, garden hose: 4-12 GPM depending on pressure and nozzle.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact since it's based on the fixed relationship between minutes and hours (1 hour = 60 minutes).
Q4: Can this conversion be used for other units?
A: Yes, the same principle applies to any flow rate conversion between per-minute and per-hour units (LPM to LPH, m³/min to m³/h, etc.).
Q5: When is GPH more useful than GPM?
A: GPH is more practical for calculating total consumption over hours or days, while GPM is better for instantaneous flow measurements and real-time control.
