GPM to GPH Formula:
| From: | To: |
The GPM to GPH conversion calculates flow rate from gallons per minute to gallons per hour. This conversion is essential in various applications where understanding hourly flow rates is necessary for system design, capacity planning, and operational efficiency.
The calculator uses the simple conversion formula:
Where:
Explanation: Since there are 60 minutes in an hour, multiplying the flow rate in gallons per minute by 60 gives the equivalent flow rate in gallons per hour.
Details: Converting between different time units of flow rate is crucial for system design, pump sizing, capacity calculations, and comparing flow rates across different time scales in hydraulic systems, irrigation, and industrial processes.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically compute the equivalent flow rate in gallons per hour (GPH).
Q1: Why convert GPM to GPH?
A: GPH is useful for calculating total volume over longer periods, system capacity requirements, and comparing flow rates when hourly measurements are more practical than minute-by-minute monitoring.
Q2: What are typical GPM values in residential applications?
A: Typical residential water flow rates range from 2-8 GPM for showers, 1.5-3 GPM for faucets, and 3-7 GPM for garden hoses.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact since it's based on the fixed relationship between minutes and hours (60 minutes = 1 hour).
Q4: Can this conversion be used for other units?
A: 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 particularly useful for calculating total daily water usage, estimating storage tank requirements, and designing systems where hourly flow rates are more relevant than instantaneous rates.
