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.

History: Developed alongside the metric system to provide precise measurements for small areas. Its importance grew with industrialization and miniaturization in technology.

Current use: Essential in engineering for measuring cross-sectional areas of wires, material thicknesses, and microelectronic components. Used in printing (dot sizes) and medical fields (blood vessel cross-sections).
