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).

Hide (hide)

Medieval EnglishHistorical unit (no longer in standard use)Approximate value

About 120 acres, the land needed to support one household. The Domesday Book assessed England in hides, but the real size varied by region.

Old English hid, tied to a word for family, named land that could support one peasant household. Bede, writing around 731, described territory by the number of families it fed, and the hide grew into the main tax unit of Anglo-Saxon England, assessed in the Domesday survey of 1086 against figures for 1066.

Treating it as an area is risky. Wikipedia calls it a measure of value rather than of size and says the old idea of a fixed 120 acres cannot be sustained, though Cambridgeshire entries do reckon a hide as 120 geld acres, which were units of assessment and not ground area. Four virgates made a hide in most counties, but Sussex used eight, and Kent counted in sulungs.

The figure used here, about 120 acres or roughly 485,600 square meters, is the traditional round number. Northern and eastern counties under Danish law used the carucate instead, nominally the same size, divided into eight oxgangs.

1 hide = 485,622.7707 square meters (approximately).
