⚠️ Common Pitfalls to Avoid

•Using the US survey acre instead of the international acre without verifying local title deeds.
•Confusing hectares (area) with linear hectometers (distance).
•Using rough estimates like '1 ha ≈ 2 acres', which creates a significant 23.5% error in property valuation.

💡 Practical Real-World Uses

•Evaluating agricultural land deeds and international farm listings.
•Planning forest conservation zones, national parks, and wildlife reserves.
•Calculating commercial real estate zoning densities and subdivision lot allocations.
