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 flow rates need to be expressed in standardized units.
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 scaling (1 million gallons = 1,000,000 gallons).
Details: Converting between GPM and MGD is crucial for water system design, regulatory compliance, pump sizing, and comparing flow rates across different time scales. MGD is commonly used in municipal water systems and large-scale industrial 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) with high precision.
Q1: Why is the conversion factor 0.00144?
A: The factor comes from: 1 GPM × 1440 minutes/day ÷ 1,000,000 = 0.00144 MGD. There are 1440 minutes in a day and 1 million gallons is 1,000,000 gallons.
Q2: When is MGD preferred over GPM?
A: MGD is typically used for large-scale water systems like municipal water treatment plants, while GPM is more common for smaller systems and pump specifications.
Q3: Can this conversion be used for any fluid?
A: Yes, the conversion is valid for any fluid measured in gallons, but it's most commonly used for water flow rates.
Q4: What's the reverse conversion (MGD to GPM)?
A: To convert MGD to GPM, multiply by 694.444 (since 1 MGD = 694.444 GPM).
Q5: How accurate is this conversion?
A: The conversion is mathematically exact. Accuracy depends on the precision of your input measurement.
