About Roods
A rood (ro) is a traditional English unit of land area equal to one quarter of an acre, or 40 square rods, approximately 1,011.71 m². Originating in medieval England, the rood was used alongside the acre and the perch for describing land ownership. The name shares its root with 'rod,' the linear unit used to measure it. While largely obsolete in modern use, roods still appear in old English legal documents, historical land surveys, and certain rural property records in England and Wales.
About Square Kilometers
A square kilometer (km²) is a metric unit of area equal to a square with sides of one kilometer (1,000 m × 1,000 m). It is used for measuring large land areas such as cities, forests, lakes, and countries. Manhattan (New York) is about 59 km², and Monaco (the second smallest country) is just over 2 km². This unit is essential in geography, urban planning, forestry, and environmental impact studies.
