Convert MLD to Cusecs (MLD to ft3/s)
1 million litres per day (MLD) = 0.4087345685 cusecs (ft³/s). 1 ft³/s = 2.446575546 MLD. Example: 15 MLD = 15 × 0.4087345685 = 6.131018528 ft³/s.

How to Convert MLD to Cusec
- 1 MLD = 0.4087345685 ft³/s
- 1 ft³/s = 2.446575546 MLD
- Example: convert 15 MLD to ft³/s: 15 MLD = 15 × 0.4087345685 ft³/s = 6.131018528 ft³/s
Formula
ft³/s = MLD × 0.4087345685357
or ft³/s = MLD ÷ 2.446575545549
Derivation from SI units:
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 cusec = 1 ft³/s = 0.028316846592 m³/s.
- 1 MLD = 0.01157407407407 m³/s ÷ 0.028316846592 m³/s per ft³/s = 0.4087345685357 ft³/s
Both units are defined exactly, so the factor is exact. MLD definition: million litres per day; Cusec definition: cusec.
Worked examples
- A reading of 20 MLD converts to 8.174691371 ft³/s.
20 MLD × 0.4087345685 = 8.174691371 ft³/s - A value of 135 MLD is 55.17916675 ft³/s.
135 MLD × 0.4087345685 = 55.17916675 ft³/s

Frequently asked questions
How many cusecs are in 1 million litres per day?
1 MLD = 0.4087345685 ft³/s.
How do I convert million litres per day to cusecs?
Multiply the value in MLD by 0.4087345685, or divide it by 2.446575546. For example, 15 MLD × 0.4087345685 = 6.131018528 ft³/s.
Is the MLD to ft³/s 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).
