How to Convert MAF to Cubic Kilometre
- 1 MAF = 1.233481838 km³
- 1 km³ = 0.8107131938 MAF
- Example: convert 15 MAF to km³: 15 MAF = 15 × 1.233481838 km³ = 18.50222756 km³
Formula
km³ = MAF × 1.233481837548
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 km³ = 10⁹ m³ = 1 BCM.
- 1 MAF = 1233.481837548 MCM ÷ 1000 MCM per km³ = 1.233481837548 km³
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; Cubic Kilometre definition: cubic kilometre.
Worked examples
- A reading of 2 MAF converts to 2.466963675 km³.
2 MAF × 1.233481838 = 2.466963675 km³ - A value of 10 MAF is 12.33481838 km³.
10 MAF × 1.233481838 = 12.33481838 km³

Where it's used
MAF are used for indus Waters Treaty and Pakistan IRSA accounts, while cubic kilometres appear in global water budgets. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.
