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 calculated over different time periods.
The calculator uses the straightforward formula:
Where:
Explanation: Since there are 60 minutes in one hour, multiplying the flow rate in gallons per minute by 60 gives you 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 flow rates across different applications. GPH is often used for longer-term flow analysis while GPM is more common for immediate flow measurements.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically compute and display the equivalent flow rate in gallons per hour (GPH).
Q1: Why convert GPM to GPH?
A: Converting to GPH helps in calculating total volume over longer periods, system capacity requirements, and comparing flow rates when different time units are used in specifications.
Q2: What are typical GPM values for common applications?
A: Residential faucets: 1-3 GPM, shower heads: 2-2.5 GPM, garden hoses: 5-10 GPM, fire hoses: 50-250 GPM.
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 calculator be used for other fluid units?
A: This specific calculator is designed for gallons. For liters or other units, you would need to convert the volume unit first before applying the time conversion.
Q5: When is GPH more useful than GPM?
A: GPH is more useful for calculating daily water usage, reservoir filling times, irrigation system requirements, and any application where flow over hours rather than minutes is relevant.
