About these units

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).

Square Wa (Thai) (sq wa)

ThaiTraditional unit (still used in some regions)

A square 2 meters on a side: exactly 4 m². Thai property prices are often quoted per square wa.

Tarang wa, the Thai name behind the English square wa, literally refers to a grid of wa. It is the smallest standard Thai land unit, the area of a square with sides of one wa, so with a wa of 2 meters it equals 4 square meters.

One hundred square wa form a ngan and 400 form a rai. Because it is so small, it is the unit in which urban plots and condominium-adjacent land are usually priced, and listings often quote a price per square wa.

Its value is the square of the wa, so any change to the wa would flow straight through, but the metric definition has been fixed since the cadastral survey of the Royal Thai Survey Department began in 1896. A typical townhouse lot of 20 square wa is therefore 80 square meters.

1 square wa (Thai) = 4 square meters (exactly).
