Tips
- 1 ha = 10,000 m² = 100 m × 100 m.
- 1 ha ≈ 2.47 acres — quick check for US/UK comparison.
- Agricultural yields quoted as tonnes/hectare are standard worldwide.
Common mistakes
- Using hectares for very small plots — m² is clearer.
- Converting acres to hectares with 2.5 factor — correct is 2.47 (1.2% error).
- Treating "a few hectares" as an exact figure in contracts — always specify.
