The candle and the foot-candle were the first defined units of light, defined in the Metropolitan Gas Act (1860). [8] The foot-candle is the intensity of light at one foot from a standard candle. The units were internationally recognized in 1881, and adopted into the metric system. [9]
The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in). The Greek foot (πούς, pous) had a length of 1 / 600 of a stadion, [12] one stadion being about 181.2 m (594 ft); [13] therefore a foot was, at the time, about 302 mm (11.9 in). Its ...

The pous (pl. podes; Ancient Greek: πούς, poús) or Greek foot (pl. feet) was a Greek unit of length of approximately 300mm or 12 inches. It had various subdivisions whose lengths varied by place and over time. 100 podes made up one plethron , 600 podes made up a stade (the Greek furlong ) and 5000 made up a milion (the Greek mile ).
A hexameter line can be divided into six feet (Greek ἕξ hex = "six"). In strict dactylic hexameter, each foot would be a dactyl (a long and two short syllables, i.e. – u u), but classical meter allows for the substitution of a spondee (two long syllables, i.e. – –) in place of a dactyl in most positions. Specifically, the first four ...
