Convert MGD (imperial) to Cusecs (MGD imp to ft3/s)
1 million imperial gallons per day (MGD (imp)) = 1.858144135 cusecs (ft³/s). 1 ft³/s = 0.5381713837 MGD (imp). Example: 15 MGD (imp) = 15 × 1.858144135 = 27.87216202 ft³/s.

How to Convert MGD (imperial) to Cusec
- 1 MGD (imp) = 1.858144135 ft³/s
- 1 ft³/s = 0.5381713837 MGD (imp)
- Example: convert 15 MGD (imp) to ft³/s: 15 MGD (imp) = 15 × 1.858144135 ft³/s = 27.87216202 ft³/s
Formula
ft³/s = MGD (imp) × 1.858144134675
Derivation from SI units:
- 1 MGD (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 MGD (imp) = 0.05261678240741 m³/s ÷ 0.028316846592 m³/s per ft³/s = 1.858144134675 ft³/s
Both units are defined exactly, so the factor is exact. MGD (imperial) definition: million imperial gallons per day; Cusec definition: cusec.
Worked examples
- A reading of 5 MGD (imp) converts to 9.290720673 ft³/s.
5 MGD (imp) × 1.858144135 = 9.290720673 ft³/s - A value of 50 MGD (imp) is 92.90720673 ft³/s.
50 MGD (imp) × 1.858144135 = 92.90720673 ft³/s
