MGD
Million US gallons per day (MGD) size water and wastewater plants in the United States; 1 MGD ≈ 3.785 MLD.
Symbol: MGD
Quantity: volumetric discharge of rivers, canals and water supply
SI relation: 1 MGD = 0.04381263638889 m³/s (exact)
Derivation: 1 MGD = 10⁶ × 3.785411784 L per day ≈ 0.0438 m³/s.
Exact: yes, by definition
Typical uses
- US treatment-plant capacity
- US water-use statistics
