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 ...
On30 uses the American O scale of 1 ⁄ 4 inch to the foot, (ratio 1:48) to operate trains on HO gauge (16.5 mm / 0.65 in) track.The 30 indicates the scale/gauge combination is used to model 2 ft 6 in (762 mm) narrow gauge prototypes, although it is often used to model 2 ft (610 mm) and 3 ft (914 mm) gauge prototypes as well.

Sn3½ is also used to represent 3 ft 6 in (1,067 mm), as the gauge is the same as HO scale. HOm uses the same 12mm gauge track to represent metre-gauge (3ft3.37in) railways. HOn3 uses 10.5 mm ( 0.413 in ) gauge to represent 3 ft ( 914 mm ) gauge railways H0e /HOn30 uses 9 mm ( 0.354 in ) gauge to represent railway with gauges of about 750 ...
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
