Convert Cumecs to MGD (imperial) (m3/s to MGD imp)
1 cumec (m³/s) = 19.00534305 million imperial gallons per day (MGD (imp)). 1 MGD (imp) = 0.05261678241 m³/s. Example: 15 m³/s = 15 × 19.00534305 = 285.0801458 MGD (imp).

How to Convert Cumec to MGD (imperial)
- 1 m³/s = 19.00534305 MGD (imp)
- 1 MGD (imp) = 0.05261678241 m³/s
- Example: convert 15 m³/s to MGD (imp): 15 m³/s = 15 × 19.00534305 MGD (imp) = 285.0801458 MGD (imp)
Formula
MGD (imp) = m³/s × 19.00534305304
Derivation from SI units:
- 1 cumec = 1 m³/s.
- 1 MGD (imp) = 10⁶ × 4.54609 L per day ≈ 0.0526 m³/s.
Both units are defined exactly, so the factor is exact. Cumec definition: cumec; MGD (imperial) definition: million imperial gallons per day.
Worked examples
- A reading of 5 m³/s converts to 95.02671527 MGD (imp).
5 m³/s × 19.00534305 = 95.02671527 MGD (imp) - A value of 100 m³/s is 1900.534305 MGD (imp).
100 m³/s × 19.00534305 = 1900.534305 MGD (imp)

Where it's used
Cumecs are used for river and flood 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.

Frequently asked questions
How many million imperial gallons per day are in 1 cumec?
1 m³/s = 19.00534305 MGD (imp).
How do I convert cumecs to million imperial gallons per day?
Multiply the value in m³/s by 19.00534305. For example, 15 m³/s × 19.00534305 = 285.0801458 MGD (imp).
Is the m³/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).
