Convert MAF to Acre-feet (MAF to acre-ft)
1 million acre-feet (MAF) = 1000000 acre-feet (acre-ft). 1 acre-ft = 0.000001 MAF. Example: 15 MAF = 15 × 1000000 = 15000000 acre-ft.

How to Convert MAF to Acre-foot
- 1 MAF = 1000000 acre-ft
- 1 acre-ft = 0.000001 MAF
- Example: convert 15 MAF to acre-ft: 15 MAF = 15 × 1000000 acre-ft = 15000000 acre-ft
Formula
acre-ft = MAF × 1000000
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 acre-foot = 43,560 ft³ = 1233.48183754752 m³.
- 1 MAF = 1233.481837548 MCM ÷ 0.001233481837548 MCM per acre-ft = 1000000 acre-ft
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; Acre-foot definition: acre-foot.
Worked examples
- A reading of 2 MAF converts to 2000000 acre-ft.
2 MAF × 1000000 = 2000000 acre-ft - A value of 10 MAF is 10000000 acre-ft.
10 MAF × 1000000 = 10000000 acre-ft

Where it's used
MAF are used for indus Waters Treaty and Pakistan IRSA accounts, while acre-feet appear in US reservoir capacity and water rights. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.
