MDG = GPM × 0.00144
| From: | To: |
The GPM to MDG conversion transforms flow rate from gallons per minute to million gallons per day. This is commonly used in water treatment, hydraulic engineering, and environmental management for large-scale flow measurements.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor is derived from the fact that there are 1,440 minutes in a day (24 hours × 60 minutes) and 1 million gallons equals 1,000,000 gallons.
Details: Converting between different flow rate units is essential for engineering calculations, system design, regulatory compliance, and comparing flow data across different measurement systems.
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 (MDG).
Q1: Why convert GPM to MDG?
A: MDG is used for large-scale water systems like municipal water supplies, wastewater treatment plants, and industrial processes where daily volumes are more meaningful than minute-to-minute flows.
Q2: What is the conversion factor derivation?
A: 1 day = 1,440 minutes, and 1 million gallons = 1,000,000 gallons, so conversion factor = 1,440 ÷ 1,000,000 = 0.00144.
Q3: When is this conversion most useful?
A: When designing water distribution systems, calculating treatment plant capacities, or meeting regulatory reporting requirements that specify daily volumes.
Q4: Are there limitations to this conversion?
A: This is a straightforward mathematical conversion assuming constant flow rates. For variable flows, average daily rates should be used.
Q5: Can this be used for other fluids besides water?
A: Yes, as long as the flow rate is measured in gallons per minute, the conversion to million gallons per day remains valid for any liquid.
