• Symbol: The symbol for square kilometer is “km²”.

• Usage: Square kilometers are frequently used in various fields, including land management, urban planning, and environmental studies, to quantify and compare land areas.

hectare

• Definition: A hectare is a metric unit of area equal to 10,000 square meters. It is primarily used in the measurement of land, particularly in agriculture and forestry.

• Symbol: The symbol for hectare is “ha”.

• Usage: Hectares are widely used in agricultural contexts for measuring large plots of land, such as farms and forests, and are recognized internationally for land measurement.

Origin of the square kilometer

• The square kilometer is derived from the metric system, which was established in France during the late 18th century. The metric system is based on powers of ten, making it easy to convert between units. The square kilometer emerged as a practical way to express large areas in a coherent and standardized format.

Origin of the hectare

• The hectare was introduced in the 18th century as part of the metric system. It was originally defined as a rectangular plot of land measuring 100 meters by 100 meters, resulting in an area of 10,000 square meters. The term “hectare” comes from the metric prefix “hecto,” meaning one hundred, combined with “are,” a unit of area equivalent to 100 square meters.
