Convert Cubic Metres to Gigalitres (m3 to GL)
1 cubic metre (m³) = 0.000001 gigalitres (GL). 1 GL = 1000000 m³. Example: 15 m³ = 15 × 0.000001 = 0.000015 GL.

How to Convert Cubic Metre to Gigalitre
- 1 m³ = 0.000001 GL
- 1 GL = 1000000 m³
- Example: convert 15 m³ to GL: 15 m³ = 15 × 0.000001 GL = 0.000015 GL
Formula
GL = m³ ÷ 1000000
Derivation from SI units:
- 1 m³ = 10⁻⁶ MCM.
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 m³ = 0.000001 MCM ÷ 1 MCM per GL = 0.000001 GL
Both units are defined exactly, so the factor is exact. Cubic Metre definition: cubic metre; Gigalitre definition: gigalitre.
Worked examples
- A reading of 1000 m³ converts to 0.001 GL.
1000 m³ × 0.000001 = 0.001 GL - A value of 100000 m³ is 0.1 GL.
100000 m³ × 0.000001 = 0.1 GL

Where it's used
Cubic Metres are used for farm ponds, tanks and check-dam storage, while gigalitres appear in australian dam storage. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.

Frequently asked questions
How many gigalitres are in 1 cubic metre?
1 m³ = 0.000001 GL.
How do I convert cubic metres to gigalitres?
Multiply the value in m³ by 0.000001, or divide it by 1000000. For example, 15 m³ × 0.000001 = 0.000015 GL.
Is the m³ to GL conversion exact?
Yes. Both units are defined exactly, and 1 m³ is exactly 0.000001 GL.
