Convert MAF to Gigalitres (MAF to GL)
1 million acre-feet (MAF) = 1233.481838 gigalitres (GL). 1 GL = 0.0008107131938 MAF. Example: 15 MAF = 15 × 1233.481838 = 18502.22756 GL.

How to Convert MAF to Gigalitre
- 1 MAF = 1233.481838 GL
- 1 GL = 0.0008107131938 MAF
- Example: convert 15 MAF to GL: 15 MAF = 15 × 1233.481838 GL = 18502.22756 GL
Formula
GL = MAF × 1233.481837548
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 MAF = 1233.481837548 MCM ÷ 1 MCM per GL = 1233.481837548 GL
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; Gigalitre definition: gigalitre.
Worked examples
- A reading of 2 MAF converts to 2466.963675 GL.
2 MAF × 1233.481838 = 2466.963675 GL - A value of 10 MAF is 12334.81838 GL.
10 MAF × 1233.481838 = 12334.81838 GL

Where it's used
MAF are used for indus Waters Treaty and Pakistan IRSA accounts, 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 million acre-feet?
1 MAF = 1233.481838 GL.
How do I convert million acre-feet to gigalitres?
Multiply the value in MAF by 1233.481838. For example, 15 MAF × 1233.481838 = 18502.22756 GL.
Is the MAF to GL conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
