Convert Cusecs to Cubic Metres per Day (ft3/s to m3/day)
1 cusec (ft³/s) = 2446.575546 cubic metres per day (m³/day). 1 m³/day = 0.0004087345685 ft³/s. Example: 15 ft³/s = 15 × 2446.575546 = 36698.63318 m³/day.

How to Convert Cusec to Cubic Metre per Day
- 1 ft³/s = 2446.575546 m³/day
- 1 m³/day = 0.0004087345685 ft³/s
- Example: convert 15 ft³/s to m³/day: 15 ft³/s = 15 × 2446.575546 m³/day = 36698.63318 m³/day
Formula
m³/day = ft³/s × 2446.575545549
Derivation from SI units:
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 m³/day = 1/86,400 m³/s; one kilolitre per day (KLD).
- 1 ft³/s = 0.028316846592 m³/s ÷ 0.00001157407407407 m³/s per m³/day = 2446.575545549 m³/day
Both units are defined exactly, so the factor is exact. Cusec definition: cusec; Cubic Metre per Day definition: cubic metre per day.
Worked examples
- A reading of 100 ft³/s converts to 244657.5546 m³/day.
100 ft³/s × 2446.575546 = 244657.5546 m³/day - A value of 5000 ft³/s is 12232877.73 m³/day.
5000 ft³/s × 2446.575546 = 12232877.73 m³/day

Where it's used
Cusecs are used for canal and dam releases in India (e.g. Cauvery releases), while cubic metres per day appear in STP and ETP capacity (KLD). Both measure volumetric discharge of rivers, canals and water supply, so the conversion is a fixed factor.

Frequently asked questions
How many cubic metres per day are in 1 cusec?
1 ft³/s = 2446.575546 m³/day.
How do I convert cusecs to cubic metres per day?
Multiply the value in ft³/s by 2446.575546. For example, 15 ft³/s × 2446.575546 = 36698.63318 m³/day.
Is the ft³/s to m³/day 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).
