About Tsubo
A tsubo (坪) is the traditional Japanese unit of floor area, equal to 400/121 m² (approximately 3.306 m²) - defined as the footprint of two tatami mats placed side by side. It has been the standard for measuring rooms and apartments in Japan for centuries and remains widely used in real estate and architecture today. Apartment sizes in Japan are routinely quoted in tsubo alongside square meters. One tsubo equals approximately 35.58 square feet or 3.95 square yards.
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.
