About these units

Square Meter (m²)

Metric (SI)Current unit

The SI unit of area: a square one meter on each side. Used for floor areas and property sizes in most of the world.

Squaring the meter was built into the metric system from the start. The French law of 18 Germinal, Year III (7 April 1795) defined the are, the land unit that gave the hectare its name, as exactly 100 square meters, so the square meter was already the foundation of metric land measure. Nobody is credited with inventing it as a separate unit. It is simply the area of a square one meter on each side, and any SI prefix that works for the meter works for it, with the prefix squared along with the unit.

That squaring catches people out: a square kilometer is one million square meters, not one thousand. Since 1983 the meter has been defined through the speed of light, so the square meter is tied to a constant of nature as well as to the second. A hectare, about the area of Trafalgar Square in London, is 10,000 square meters. In everyday terms one square meter is about 10.76 square feet. Unicode has a compatibility character for it, but the recommended way to write it is the plain superscript two: m².

The square meter is the reference unit for area on this site.

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).
