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).

Dunam (dunam)

Middle EasternTraditional unit (still used in some regions)

Exactly 1,000 m² in the modern metric standard. Older Ottoman dunams varied by region, from about 900 to 2,500 m².

Ottoman Turkish dönmek means to turn, and the dunam probably follows the Byzantine Greek stremma, a land measure of similar size. Its legal definition was forty standard paces in length and breadth, but the real area differed from province to province, from just over 900 square meters in Ottoman Palestine to about 2,500 in Ottoman Iraq. Roughly it matched the land an ox team could plough in a day.

Today the metric dunam is standardised at exactly 1,000 square meters, a tenth of a hectare, and that is the figure used here. It is the working unit in Israel, Palestine, Syria, Iraq and Turkey, and the Balkan dunam is mostly the same, with local exceptions such as about 1,600 square meters around Leskovac in Serbia. Under the British Mandate the dunam was 919.3 square meters until the metric version was adopted in 1928. Cyprus lists its donum at 1,338 square meters, and the old Ottoman stremma in Greece is given as about 1,270.

1 dunam = 1,000 square meters (exactly).
