Convert Cubic Metres per Day to MLD (m3/day to MLD)
1 cubic metre per day (m³/day) = 0.001 million litres per day (MLD). 1 MLD = 1000 m³/day. Example: 15 m³/day = 15 × 0.001 = 0.015 MLD.

How to Convert Cubic Metre per Day to MLD
- 1 m³/day = 0.001 MLD
- 1 MLD = 1000 m³/day
- Example: convert 15 m³/day to MLD: 15 m³/day = 15 × 0.001 MLD = 0.015 MLD
Formula
MLD = m³/day ÷ 1000
Derivation from SI units:
- 1 m³/day = 1/86,400 m³/s; one kilolitre per day (KLD).
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 m³/day = 0.00001157407407407 m³/s ÷ 0.01157407407407 m³/s per MLD = 0.001 MLD
Both units are defined exactly, so the factor is exact. Cubic Metre per Day definition: cubic metre per day; MLD definition: million litres per day.
Worked examples
- A reading of 500 m³/day converts to 0.5 MLD.
500 m³/day × 0.001 = 0.5 MLD - A value of 10000 m³/day is 10 MLD.
10000 m³/day × 0.001 = 10 MLD

Where it's used
Cubic Metres per Day are used for STP and ETP capacity (KLD), while million litres per day appear in water treatment and sewage plant capacity. Both measure volumetric discharge of rivers, canals and water supply, so the conversion is a fixed factor.

Frequently asked questions
How many million litres per day are in 1 cubic metre per day?
1 m³/day = 0.001 MLD.
How do I convert cubic metres per day to million litres per day?
Multiply the value in m³/day by 0.001, or divide it by 1000. For example, 15 m³/day × 0.001 = 0.015 MLD.
Is the m³/day to MLD conversion exact?
Yes. Both units are defined exactly, and 1 m³/day is exactly 0.001 MLD.
