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 Chains
A square chain (ch²) is a surveying unit equal to the area of a square with sides of one Gunter's chain (66 feet or ~20.12 m), approximately 404.69 m². Ten square chains equal exactly one acre, making it the natural subdivision unit in traditional land surveying. The US Public Land Survey System used chains to lay out townships and sections, and square chains appear throughout old legal property descriptions and government land grants across North America. One square chain equals exactly 16 square rods.
