Tips & common mistakes

Quick 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.

Avoid these

  • 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.
