GPM to MGD Conversion Formula:
| From: | To: |
The GPM to MGD conversion is used to convert flow rates from gallons per minute to million gallons per day. This conversion is essential in water treatment, hydraulic engineering, and environmental management where large-scale water flow measurements are required.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 0.00144 is derived from the relationship between minutes and days (1 day = 1440 minutes) and the million-gallon unit (1 MGD = 1,000,000 gallons per day).
Details: Converting between GPM and MGD is crucial for water system design, regulatory compliance, pump sizing, and treatment plant capacity planning. MGD is commonly used for large-scale municipal water systems, while GPM is often used for smaller applications.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically convert it to million gallons per day (MGD).
Q1: Why convert GPM to MGD?
A: MGD is the standard unit for reporting large water flows in municipal water systems, treatment plants, and regulatory reporting, while GPM is more practical for smaller-scale measurements.
Q2: How is the conversion factor calculated?
A: 1 GPM = 1 gallon/minute × 1440 minutes/day ÷ 1,000,000 = 0.00144 MGD
Q3: What are typical GPM values for different applications?
A: Residential faucets: 1-3 GPM, shower heads: 2-3 GPM, municipal pumps: 100-10,000+ GPM, large treatment plants: 1-100+ MGD.
Q4: Can this calculator be used for other fluids besides water?
A: Yes, the conversion is valid for any fluid measured in gallons, but ensure the gallon unit (US gallon vs Imperial gallon) is consistent.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input GPM measurement.
