How to Convert MAF to MCM
- 1 MAF = 1233.481838 MCM
- 1 MCM = 0.0008107131938 MAF
- Example: convert 15 MAF to MCM: 15 MAF = 15 × 1233.481838 MCM = 18502.22756 MCM
Formula
MCM = MAF × 1233.481837548
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 MCM = 10⁶ m³ = 1 hm³ (cubic hectometre).
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; MCM definition: million cubic metres.
Worked examples
- A reading of 2 MAF converts to 2466.963675 MCM.
2 MAF × 1233.481838 = 2466.963675 MCM - A value of 10 MAF is 12334.81838 MCM.
10 MAF × 1233.481838 = 12334.81838 MCM
