Convert MAF to Hectare-metres (MAF to ha-m)
1 million acre-feet (MAF) = 123348.1838 hectare-metres (ha·m). 1 ha·m = 0.000008107131938 MAF. Example: 15 MAF = 15 × 123348.1838 = 1850222.756 ha·m.

How to Convert MAF to Hectare-metre
- 1 MAF = 123348.1838 ha·m
- 1 ha·m = 0.000008107131938 MAF
- Example: convert 15 MAF to ha·m: 15 MAF = 15 × 123348.1838 ha·m = 1850222.756 ha·m
Formula
ha·m = MAF × 123348.1837548
Derivation from SI units:
- 1 MAF = 10⁶ acre-feet = 1233.48 MCM.
- 1 ha·m = 10,000 m² × 1 m = 10⁴ m³ = 0.01 MCM.
- 1 MAF = 1233.481837548 MCM ÷ 0.01 MCM per ha·m = 123348.1837548 ha·m
Both units are defined exactly, so the factor is exact. MAF definition: million acre-feet; Hectare-metre definition: hectare-metre.
Worked examples
- A reading of 2 MAF converts to 246696.3675 ha·m.
2 MAF × 123348.1838 = 246696.3675 ha·m - A value of 10 MAF is 1233481.838 ha·m.
10 MAF × 123348.1838 = 1233481.838 ha·m

Where it's used
MAF are used for indus Waters Treaty and Pakistan IRSA accounts, while hectare-metres appear in crop water requirement and duty–delta problems. Both measure volume of stored or released water (reservoirs, river flows, allocations), so the conversion is a fixed factor.

Frequently asked questions
How many hectare-metres are in 1 million acre-feet?
1 MAF = 123348.1838 ha·m.
How do I convert million acre-feet to hectare-metres?
Multiply the value in MAF by 123348.1838. For example, 15 MAF × 123348.1838 = 1850222.756 ha·m.
Is the MAF to ha·m 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).
