Accuracy
This tool uses the WGS84 coordinate system and calculates geodesic area, which accounts for the Earth's curvature. For most practical purposes, the measurements are highly accurate.
For legal or surveying purposes, always verify measurements with a professional surveyor. This tool is designed for estimates and general planning, not legal documentation.
