The foot of an adult European-American male is typically about 15.3% of his height, [10] giving a person of 175 cm (5 ft 9 in) a foot-length of about 268 mm (10.6 in), on average. Archaeologists believe that, in the past, the people of Egypt , India , and Mesopotamia preferred the cubit , while the people of Rome , Greece , and China preferred ...
The recent formula used by the Brannock device assumes a foot length of 2 barleycorns less than the length of the last; thus, men's size 1 is equivalent to a last's length of 8 + 1 ⁄ 3 in (21.17 cm) and foot's length of 7 + 2 ⁄ 3 in (19.47 cm), and children's size 1 is equivalent to 4 + 1 ⁄ 4 in (10.8 cm) last's length and 3 + 7 ⁄ 12 in ...

He proposed calling his base unit of length a "foot" which he suggested should be either 3 ⁄ 10 or 1 ⁄ 3 of the length of a pendulum that had a period of one second—that is 3 ⁄ 10 or 1 ⁄ 3 of the "standard" proposed by John Wilkins over a century previously. This would have equated to 11.755 English inches (29.8 cm) or 13.06 English ...
