About Square Furlongs
A square furlong is an area unit equal to a square with sides of one furlong (220 yards or ~201.17 m), approximately 40,469 m² or exactly 10 acres. The furlong (from Old English 'furrow-long') was historically the standard ploughing distance, and 10 square furlongs equals one acre - a relationship that made traditional land surveying convenient. While square furlongs are rarely used in official modern measurements, they appear in historical land surveys, British horse racing contexts, and as a handy reference for visualising 10-acre blocks.
About Ares
An are (a) is a metric unit of area equal to 100 square meters (10 m × 10 m). Though less commonly used today, it served as an intermediate unit between square meters and hectares in the metric system. One are equals 0.01 hectares or about 119.6 yd². It is still occasionally used in some European countries for measuring medium-sized land plots, gardens, and vineyards. The dekameter-squared (dam²) is another name for the same unit.
