Convert Cubic Metres to Megalitres (m3 to ML)
1 cubic metre (m³) = 0.001 megalitres (ML). 1 ML = 1000 m³. Example: 15 m³ = 15 × 0.001 = 0.015 ML.

How to Convert Cubic Metre to Megalitre
- 1 m³ = 0.001 ML
- 1 ML = 1000 m³
- Example: convert 15 m³ to ML: 15 m³ = 15 × 0.001 ML = 0.015 ML
Formula
ML = m³ ÷ 1000
Derivation from SI units:
- 1 m³ = 10⁻⁶ MCM.
- 1 ML = 10⁶ L = 1000 m³.
- 1 m³ = 0.000001 MCM ÷ 0.001 MCM per ML = 0.001 ML
Both units are defined exactly, so the factor is exact. Cubic Metre definition: cubic metre; Megalitre definition: megalitre.
Worked examples
- A reading of 1000 m³ converts to 1 ML.
1000 m³ × 0.001 = 1 ML - A value of 100000 m³ is 100 ML.
100000 m³ × 0.001 = 100 ML

Where it's used
Cubic Metres are used for farm ponds, tanks and check-dam storage, 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.

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