About Square Micrometers
A square micrometer (μm²), also called a square micron, equals one trillionth of a square meter - the area of a square with sides one millionth of a meter (10⁻¹² m²). This is the natural scale of biological cells: a human red blood cell has a surface area of about 135 μm², and a typical bacterium might occupy 2-10 μm². Square micrometers are the standard unit in cell biology, histology, microscopy, and semiconductor characterisation where individual features on wafers are measured.
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.
