How to Convert Cusec to MGD (imperial)
- 1 ft³/s = 0.5381713837 MGD (imp)
- 1 MGD (imp) = 1.858144135 ft³/s
- Example: convert 15 ft³/s to MGD (imp): 15 ft³/s = 15 × 0.5381713837 MGD (imp) = 8.072570755 MGD (imp)
Formula
MGD (imp) = ft³/s × 0.5381713836613
or MGD (imp) = ft³/s ÷ 1.858144134675
Derivation from SI units:
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 MGD (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
- 1 ft³/s = 0.028316846592 m³/s ÷ 0.05261678240741 m³/s per MGD (imp) = 0.5381713836613 MGD (imp)
Both units are defined exactly, so the factor is exact. Cusec definition: cusec; MGD (imperial) definition: million imperial gallons per day.
Worked examples
- A reading of 100 ft³/s converts to 53.81713837 MGD (imp).
100 ft³/s × 0.5381713837 = 53.81713837 MGD (imp) - A value of 5000 ft³/s is 2690.856918 MGD (imp).
5000 ft³/s × 0.5381713837 = 2690.856918 MGD (imp)

Where it's used
Cusecs are used for canal and dam releases in India (e.g. Cauvery releases), 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.

Frequently asked questions
How many million imperial gallons per day are in 1 cusec?
1 ft³/s = 0.5381713837 MGD (imp).
How do I convert cusecs to million imperial gallons per day?
Multiply the value in ft³/s by 0.5381713837, or divide it by 1.858144135. For example, 15 ft³/s × 0.5381713837 = 8.072570755 MGD (imp).
Is the ft³/s to MGD (imp) conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
