About Pyeong

A pyeong (평) is the traditional Korean unit of floor area, equal to approximately 3.306 m² - historically derived from the Japanese tsubo, with which it shares the same value. Despite South Korea officially adopting square meters, pyeong remains deeply embedded in Korean real estate culture. Apartment listings in Seoul and Busan still commonly advertise sizes in pyeong, and a typical Korean family apartment is around 25-33 pyeong. One pyeong equals approximately 35.58 square feet.

About Square Millimeters

A square millimeter (mm²) is a metric unit of area equal to a square with sides of one millimeter. It is commonly used in precision engineering, electronics, and measuring very small surfaces such as microchips or printed circuit boards. To visualise: a typical pinhead has an area of about 2-3 mm². This unit is essential in microscopy, medical imaging, and manufacturing where tiny, precise measurements are critical.
