Convert MLD to Cubic Metres per Day (MLD to m3/day)
1 million litres per day (MLD) = 1000 cubic metres per day (m³/day). 1 m³/day = 0.001 MLD. Example: 15 MLD = 15 × 1000 = 15000 m³/day.

How to Convert MLD to Cubic Metre per Day
- 1 MLD = 1000 m³/day
- 1 m³/day = 0.001 MLD
- Example: convert 15 MLD to m³/day: 15 MLD = 15 × 1000 m³/day = 15000 m³/day
Formula
m³/day = MLD × 1000
Derivation from SI units:
- 1 MLD = 10⁶ L/day = 1000 m³/day = 1000/86,400 m³/s.
- 1 m³/day = 1/86,400 m³/s; one kilolitre per day (KLD).
- 1 MLD = 0.01157407407407 m³/s ÷ 0.00001157407407407 m³/s per m³/day = 1000 m³/day
Both units are defined exactly, so the factor is exact. MLD definition: million litres per day; Cubic Metre per Day definition: cubic metre per day.
Worked examples
- A reading of 20 MLD converts to 20000 m³/day.
20 MLD × 1000 = 20000 m³/day - A value of 135 MLD is 135000 m³/day.
135 MLD × 1000 = 135000 m³/day

Where it's used
MLD are used for water treatment and sewage plant capacity, 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 million litres per day?
1 MLD = 1000 m³/day.
How do I convert million litres per day to cubic metres per day?
Multiply the value in MLD by 1000. For example, 15 MLD × 1000 = 15000 m³/day.
Is the MLD to m³/day conversion exact?
Yes. Both units are defined exactly, and 1 MLD is exactly 1000 m³/day.
