Convert BCM to Megalitres (BCM to ML)
1 billion cubic metres (BCM) = 1000000 megalitres (ML). 1 ML = 0.000001 BCM. Example: 15 BCM = 15 × 1000000 = 15000000 ML.

How to Convert BCM to Megalitre
- 1 BCM = 1000000 ML
- 1 ML = 0.000001 BCM
- Example: convert 15 BCM to ML: 15 BCM = 15 × 1000000 ML = 15000000 ML
Formula
ML = BCM × 1000000
Derivation from SI units:
- 1 BCM = 10⁹ m³ = 1000 MCM = 1 km³.
- 1 ML = 10⁶ L = 1000 m³.
- 1 BCM = 1000 MCM ÷ 0.001 MCM per ML = 1000000 ML
Both units are defined exactly, so the factor is exact. BCM definition: billion cubic metres; Megalitre definition: megalitre.
Worked examples
- A reading of 2 BCM converts to 2000000 ML.
2 BCM × 1000000 = 2000000 ML - A value of 30 BCM is 30000000 ML.
30 BCM × 1000000 = 30000000 ML

Where it's used
BCM are used for national water resources assessments, while megalitres appear in australian water entitlements. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.
