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 Decimeters
A square decimeter (dm²) is a metric area unit equal to 100 square centimeters (10 cm × 10 cm) or 0.01 square meters. It represents roughly the footprint of a large paperback book or a standard floor tile. While less common in everyday language than cm² or m², square decimeters appear in cooking (pan sizes), packaging design, and as a useful stepping stone in metric calculations - notably, exactly 1 liter of liquid forms a layer 1 dm² × 1 cm deep.
