About these units

Pyeong (py)

KoreanTraditional unit (still used in some regions)

Exactly 400/121 m² (3.3058 m²), the Korean unit equivalent to the Japanese tsubo and the Taiwanese ping. Still used informally for apartment sizes in Korea and Taiwan.

Floor space in South Korea is still often quoted in pyeong, a word that, like the Japanese tsubo and Taiwanese ping, stands for a square whose side is one kan or bu, equal to 36 square Chinese or Japanese feet. The Korean version was fixed during the Japanese occupation at 400/121 square meters, about 3.3058 square meters, which is roughly the area of two tatami mats.

Korean sources use the pyeong as the standard traditional measure for homes. Typical benchmarks are about 25 pyeong for an average house and 8 to 12 for a studio flat. Official use was banned in 1961, but the ban had little effect until commercial use was criminalised from 1 July 2007, after which listings show square meters with the pyeong figure as an informal extra. Taiwan introduced the ping under Japanese rule and still uses it, at about 3.305 square meters. Wikipedia notes that a Chinese version based on metric feet would be near 4 square meters but is almost unknown.

1 pyeong = 3.305785124 square meters (approximately).

Square Foot (ft²)

US & ImperialCurrent unit

Exactly 0.09290304 m². The standard unit for floor areas and real estate in the US, UK and India.

Feet came first, and they were not all the same length. As a body-based unit, the foot ranged historically between about 250 and 335 millimeters, with ancient Greek and Roman feet near 300 mm. In medieval England a statute foot was set at 10/11 of an older Belgic foot, and Charlemagne's attempt around 790 to standardize units largely failed. The square foot is simply that length squared, so its size changed along with the foot.

The 1959 international agreement fixed the foot at exactly 0.3048 meter, so one square foot is exactly 0.09290304 m², or 144 square inches. The United Kingdom adopted the new foot in 1964. Today the square foot is the usual way of listing property in the United States, Canada, the United Kingdom, India, Pakistan, Singapore and Hong Kong, although the measuring convention varies: agents may measure corner to corner, subtract unheated space, or add heated space that extends beyond the end-to-end measurement. The world's smallest park has been reported at 2.6 sq ft.

1 square foot = 0.09290304 square meters (exactly).
