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).

Feddan (fd)

Middle EasternTraditional unit (still used in some regions)Approximate value

About 4,200 m² (1.037 acres). The standard unit of farmland in Egypt, divided into 24 qirat.

In Classical Arabic faddan meant a yoke of oxen, so the name points to the ground a team could plough in a season. That idea explains why the feddan was never a single fixed size everywhere: in Syria it stayed vague, covering roughly 5 to 12 hectares of land worked by a pair of oxen over a year.

Egypt gave it a precise value. The metric system became optional there in 1873 and compulsory for government use in 1891, and the 1891 equivalences set the feddan near 4,200.8 square metres. The main Wikipedia article rounds this to 4,200 square metres, based on a plot of 60 by 70 metres, and the figure used here follows that article. The two readings differ by well under a tenth of a percent, or about 1.04 acres.

The feddan is divided into 24 qirat, each about 175 square metres, with a finer sahm equal to one 576th of a feddan. It was the one non-metric unit that stayed in everyday use in Egypt after metrication, and it is still the normal measure for farmland there, with use in Sudan, South Sudan and Oman as well.

1 feddan = 4,200 square meters (approximately).
