Definition: An acre (symbol: ac) is a unit of land area equal to 4,046.8564224 square meters, 43,560 square feet, or 1/640 of a square mile.
History/origin: The acre dates back to medieval England, where it was roughly the amount of land a team of oxen could plough in a day. It remained a practical land unit even after formal standardization.
Current use: Acres are widely used in the United States, Canada, and the UK for farmland, rural property, estates, and large plots of land.
Definition: The hectare is a large metric land unit. It equals 10,000 m², so a square plot 100 meters on each side has an area of one hectare.
History/origin: Metric land measurement needed a unit more manageable than square meters for fields and estates, and the hectare filled that role through the are-based metric system.
Current use: Ha is common in agricultural reports, conservation areas, forestry, vineyards, land registries, planning documents, and international comparisons of property or habitat size.
