Hectare
Definition: A hectare (symbol: ha) is a metric unit of area equal to 10,000 square meters (100m × 100m) or approximately 2.471 acres. It is the most commonly used unit for measuring land area in the metric system.
History: Introduced in 1795 as part of the original metric system in France, using the Greek 'hecto-' (hundred) prefix with the are (100 square meters). The hectare became 100 ares, providing a practical unit for land measurement.
Current use: The standard unit for agricultural land, forestry, and urban planning in metric countries. Used worldwide in official land records except in the United States. Common in environmental science and land management.

History: Developed as part of the metric system's decimal-based scaling, the square kilometer became particularly useful for geographical measurements. Its adoption grew with the metric system's international acceptance in the 19th and 20th centuries.
Current use: Primarily used to measure large land areas such as cities, national parks, and countries. Commonly appears in geographical surveys, urban planning, and environmental studies. Most world maps and atlases use square kilometers, though some US publications still use square miles.
