Convert Litres per Second to MGD (imperial) (L/s to MGD imp)

Formula

MGD (imp) = L/s × 0.01900534305304

or MGD (imp) = L/s ÷ 52.61678240741

Derivation from SI units:

• 1 L/s = 10⁻³ m³/s.
• 1 MGD (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
• 1 L/s = 0.001 m³/s ÷ 0.05261678240741 m³/s per MGD (imp) = 0.01900534305304 MGD (imp)

Both units are defined exactly, so the factor is exact. Litre per Second definition: litre per second; MGD (imperial) definition: million imperial gallons per day.

Worked examples

1. A reading of 5 L/s converts to 0.09502671527 MGD (imp).
   5 L/s × 0.01900534305 = 0.09502671527 MGD (imp)
2. A value of 50 L/s is 0.9502671527 MGD (imp).
   50 L/s × 0.01900534305 = 0.9502671527 MGD (imp)

Where it's used

Litres per Second are used for tube-well and pump discharge, while million imperial gallons per day appear in older Indian municipal records. Both measure volumetric discharge of rivers, canals and water supply, so the conversion is a fixed factor.
