GPM = GPH / 60
| From: | To: |
The GPH to GPM conversion calculates flow rate from gallons per hour to gallons per minute. This conversion is essential for various applications including fluid dynamics, plumbing, irrigation systems, and industrial processes where flow rates need to be compared or standardized across different time units.
The calculator uses the simple conversion formula:
Where:
Explanation: Since there are 60 minutes in one hour, dividing the hourly flow rate by 60 gives the equivalent flow rate per minute.
Details: Converting between different time units for flow rates is crucial for system design, pump selection, pipe sizing, and ensuring proper fluid delivery in various engineering and industrial applications.
Tips: Enter the flow rate in gallons per hour (GPH). The value must be positive. The calculator will automatically compute the equivalent flow rate in gallons per minute (GPM).
Q1: Why convert GPH to GPM?
A: Different applications require flow rates in different time units. GPM is often used for pump specifications and system design, while GPH may be used for longer-term flow measurements.
Q2: What is the typical range for GPH values?
A: GPH values can range from very small (drip irrigation: 0.1-10 GPH) to very large (industrial processes: thousands of GPH).
Q3: Can this conversion be used for other fluids besides water?
A: Yes, the conversion is unit-based and works for any fluid measured in gallons, as long as the density differences don't affect the volumetric flow rate measurement.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact since it's based on the fixed relationship between hours and minutes (1 hour = 60 minutes).
Q5: What are common applications for GPH to GPM conversion?
A: Irrigation system design, fuel flow calculations, chemical dosing systems, water treatment plants, and hydraulic system analysis.
