How to Convert Cusec to MLD
- 1 ft³/s = 2.446575546 MLD
- 1 MLD = 0.4087345685 ft³/s
- Example: convert 1 ft³/s to MLD: 1 ft³/s = 1 × 2.446575546 MLD = 2.446575546 MLD
Formula
MLD = ft³/s × 2.446575545549
Derivation from SI units:
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 ft³/s = 0.028316846592 m³/s ÷ 0.01157407407407 m³/s per MLD = 2.446575545549 MLD
Both units are defined exactly, so the factor is exact. Cusec definition: cusec; MLD definition: million litres per day.
Worked examples
- 1 ft³/s is 2.446575546 MLD.
1 ft³/s × 2.446575546 = 2.446575546 MLD - A canal supply of 100 ft³/s is 244.6575546 MLD.
100 ft³/s × 2.446575546 = 244.6575546 MLD

Frequently asked questions
How many MLD is 1 cusec?
1 cusec = 2.446575546 MLD.
How many million litres per day are in 1 cusec?
1 ft³/s = 2.446575546 MLD.
How do I convert cusecs to million litres per day?
Multiply the value in ft³/s by 2.446575546. For example, 1 ft³/s × 2.446575546 = 2.446575546 MLD.
Is the ft³/s to MLD 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).
