Convert MCM to Megalitres (MCM to ML)
1 million cubic metres (MCM) = 1000 megalitres (ML). 1 ML = 0.001 MCM. Example: 15 MCM = 15 × 1000 = 15000 ML.

How to Convert MCM to Megalitre
- 1 MCM = 1000 ML
- 1 ML = 0.001 MCM
- Example: convert 15 MCM to ML: 15 MCM = 15 × 1000 ML = 15000 ML
Formula
ML = MCM × 1000
Derivation from SI units:
- 1 MCM = 10⁶ m³ = 1 hm³ (cubic hectometre).
- 1 ML = 10⁶ L = 1000 m³.
Both units are defined exactly, so the factor is exact. MCM definition: million cubic metres; Megalitre definition: megalitre.
Worked examples
- A reading of 5 MCM converts to 5000 ML.
5 MCM × 1000 = 5000 ML - A value of 100 MCM is 100000 ML.
100 MCM × 1000 = 100000 ML
