History and Interesting Facts

Hectares and acres are both units of area measurement. The hectare, a metric unit, is commonly used worldwide, particularly in agriculture and land planning. The acre, an imperial unit, is used mainly in the United States, the United Kingdom, and a few other countries. Historically, an acre was defined as the amount of land that could be plowed in one day by a team of oxen. The hectare, being part of the metric system, is a newer and more standardized unit of measurement.
