Convert Gigalitres to MAF (GL to MAF)
1 gigalitre (GL) = 0.0008107131938 million acre-feet (MAF). 1 MAF = 1233.481838 GL. Example: 15 GL = 15 × 0.0008107131938 = 0.01216069791 MAF.

How to Convert Gigalitre to MAF
- 1 GL = 0.0008107131938 MAF
- 1 MAF = 1233.481838 GL
- Example: convert 15 GL to MAF: 15 GL = 15 × 0.0008107131938 MAF = 0.01216069791 MAF
Formula
MAF = GL × 0.0008107131937899
or MAF = GL ÷ 1233.481837548
Derivation from SI units:
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 GL = 1 MCM ÷ 1233.481837548 MCM per MAF = 0.0008107131937899 MAF
Both units are defined exactly, so the factor is exact. Gigalitre definition: gigalitre; MAF definition: million acre-feet.
Worked examples
- A reading of 5 GL converts to 0.004053565969 MAF.
5 GL × 0.0008107131938 = 0.004053565969 MAF - A value of 100 GL is 0.08107131938 MAF.
100 GL × 0.0008107131938 = 0.08107131938 MAF

Frequently asked questions
How many million acre-feet are in 1 gigalitre?
1 GL = 0.0008107131938 MAF.
How do I convert gigalitres to million acre-feet?
Multiply the value in GL by 0.0008107131938, or divide it by 1233.481838. For example, 15 GL × 0.0008107131938 = 0.01216069791 MAF.
Is the GL to MAF 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).
