How to Convert MLD to MGD
- 1 MLD = 0.2641720524 MGD
- 1 MGD = 3.785411784 MLD
- Example: convert 100 MLD to MGD: 100 MLD = 100 × 0.2641720524 MGD = 26.41720524 MGD
Formula
MGD = MLD × 0.2641720523581
or MGD = MLD ÷ 3.785411784
Derivation from SI units:
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 MGD = 10⁶ × 3.785411784 L per day ≈ 0.0438 m³/s.
- 1 MLD = 0.01157407407407 m³/s ÷ 0.04381263638889 m³/s per MGD = 0.2641720523581 MGD
Both units are defined exactly, so the factor is exact. MLD definition: million litres per day; MGD definition: million US gallons per day.
Worked examples
- A plant of 100 MLD is 26.41720524 MGD.
100 MLD × 0.2641720524 = 26.41720524 MGD - 1 MLD is 0.2641720524 MGD.
1 MLD × 0.2641720524 = 0.2641720524 MGD
