How to Convert MLD to MGD (imperial)
- 1 MLD = 0.2199692483 MGD (imp)
- 1 MGD (imp) = 4.54609 MLD
- Example: convert 15 MLD to MGD (imp): 15 MLD = 15 × 0.2199692483 MGD (imp) = 3.299538724 MGD (imp)
Formula
MGD (imp) = MLD × 0.2199692482991
or MGD (imp) = MLD ÷ 4.54609
Derivation from SI units:
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 MGD (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
- 1 MLD = 0.01157407407407 m³/s ÷ 0.05261678240741 m³/s per MGD (imp) = 0.2199692482991 MGD (imp)
Both units are defined exactly, so the factor is exact. MLD definition: million litres per day; MGD (imperial) definition: million imperial gallons per day.
Worked examples
- A reading of 20 MLD converts to 4.399384966 MGD (imp).
20 MLD × 0.2199692483 = 4.399384966 MGD (imp) - A value of 135 MLD is 29.69584852 MGD (imp).
135 MLD × 0.2199692483 = 29.69584852 MGD (imp)
