About these units
Square Kilometer (km²)
A square kilometer equals one million square meters and is the standard unit for expressing large land areas, especially in geography, ecology, national planning, and environmental science. Countries, cities, national parks, forests, wetlands, and even ocean surface regions are frequently described in km². Because it provides a manageable scale for features too large for hectares or acres, it is widely used in atlases, scientific papers, and government reports. The square kilometer also plays a major role in ecology, where species ranges, habitat fragmentation, and conservation zones are measured using this unit. In geopolitics, km² help define national borders and territorial claims, making it a powerful instrument of scientific and political discourse.
Rood (rood)
A rood equals 1/4 of an acre, or 10,890 square feet, and was used in medieval and early modern England for land measurement. The rood often appeared in agricultural records, taxation documents, and estate descriptions. Farmers used the rood to describe smaller plots of arable land, orchards, and grazing fields. Although obsolete today, the rood reflects the practical needs of historical agrarian societies, where manageable sub-acres allowed fine-grained recordkeeping and land division within larger estates.
