How to Convert Cubic Metre to MAF
- 1 m³ = 8.107131938 × 10⁻¹⁰ MAF
- 1 MAF = 1233481838 m³
- Example: convert 15 m³ to MAF: 15 m³ = 15 × 8.107131938 × 10⁻¹⁰ MAF = 1.216069791 × 10⁻⁸ MAF
Formula
MAF = m³ × 8.107131937899 × 10⁻¹⁰
or MAF = m³ ÷ 1233481837.548
Derivation from SI units:
- 1 m³ = 10⁻⁶ MCM.
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 m³ = 0.000001 MCM ÷ 1233.481837548 MCM per MAF = 8.107131937899 × 10⁻¹⁰ MAF
Both units are defined exactly, so the factor is exact. Cubic Metre definition: cubic metre; MAF definition: million acre-feet.
Worked examples
- A reading of 1000 m³ converts to 8.107131938 × 10⁻⁷ MAF.
1000 m³ × 8.107131938 × 10⁻¹⁰ = 8.107131938 × 10⁻⁷ MAF - A value of 100000 m³ is 0.00008107131938 MAF.
100000 m³ × 8.107131938 × 10⁻¹⁰ = 0.00008107131938 MAF

Where it's used
Cubic Metres are used for farm ponds, tanks and check-dam storage, while million acre-feet appear in indus Waters Treaty and Pakistan IRSA accounts. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.

Frequently asked questions
How many million acre-feet are in 1 cubic metre?
1 m³ = 8.107131938 × 10⁻¹⁰ MAF.
How do I convert cubic metres to million acre-feet?
Multiply the value in m³ by 8.107131938 × 10⁻¹⁰, or divide it by 1233481838. For example, 15 m³ × 8.107131938 × 10⁻¹⁰ = 1.216069791 × 10⁻⁸ MAF.
Is the m³ 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).
