Convert MAF to Cubic Metres (MAF to m3)
1 million acre-feet (MAF) = 1233481838 cubic metres (m³). 1 m³ = 8.107131938 × 10⁻¹⁰ MAF. Example: 15 MAF = 15 × 1233481838 = 18502227560 m³.

How to Convert MAF to Cubic Metre
- 1 MAF = 1233481838 m³
- 1 m³ = 8.107131938 × 10⁻¹⁰ MAF
- Example: convert 15 MAF to m³: 15 MAF = 15 × 1233481838 m³ = 18502227560 m³
Formula
m³ = MAF × 1233481837.548
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 m³ = 10⁻⁶ MCM.
- 1 MAF = 1233.481837548 MCM ÷ 0.000001 MCM per m³ = 1233481837.548 m³
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; Cubic Metre definition: cubic metre.
Worked examples
- A reading of 2 MAF converts to 2466963675 m³.
2 MAF × 1233481838 = 2466963675 m³ - A value of 10 MAF is 12334818380 m³.
10 MAF × 1233481838 = 12334818380 m³

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