Although most contemporary accounts used an Arabic mile of 6 444 feet (1,964 metres), which gave a Spanish league of the degree of 25,776 feet (7,857 metres or 4.242 modern nautical miles) others defined an Arabic mile as just 6,000 feet making a Spanish league of the degree 24,000 feet (or 7,315 metres, almost exactly 3.95 modern nautical miles).
Under Marcus Vipsanius Agrippa, it was standardized as the distance of two steps (gradūs) or five Roman feet (pedes), about 1.48 meters or 4 feet 10 inches. One thousand paces were described simply as mille passus or passuum , now known as a Roman mile ; this is the origin of the English term "mile".
Alternatively, the rule can be used to determine the equivalent flat distance of a route. This is achieved by recognising that Naismith's rule implies an equivalence between distance and climb in time terms: 3 miles (=15,840 feet) of distance is equivalent in time terms to 2000 feet of climb. [17]
"There are about 2,000 steps in a mile with an approximate stride length of 2 feet-ish," says Colleen M. Brough, PT, DPT, MS, board certified orthopedic clinical specialist and director of ...

Clock time and calendar time have duodecimal or sexagesimal orders of magnitude rather than decimal, e.g., a year is 12 months, and a minute is 60 seconds. The smallest meaningful increment of time is the Planck time―the time light takes to traverse the Planck distance, many decimal orders of magnitude smaller than a second. [1]
The Tueller Drill is a self-defense training exercise to prepare against a short-range knife or melee attack when armed only with a holstered handgun.. Sergeant Dennis Tueller of the Salt Lake City Police Department wondered how quickly an attacker with a knife, or other melee weapon, could cover 21 feet (6.4 m), so he timed volunteers as they raced to stab the target.
Respectively, these square divisions of land are approximately 80 chains (one mile or 1.6 km), 40 chains (half a mile or 800 m), and 20 chains (a quarter mile or 400 m) on a side. The chain is still used in agriculture: measuring wheels with a circumference of 0.1 chain (diameter ≈ 2.1 ft or 64 cm) are still readily available in Canada and ...
