W = walking velocity [km/h] [2] dh = elevation difference, dx = distance, S = slope, θ = angle of slope (inclination). The velocity on the flat terrain is 5 km / h, the maximum speed of 6 km / h is achieved roughly at -2.86°. [5] On flat terrain this formula works out to 5 km/h.
The preferred walking speed is the speed at which humans or animals choose to walk. Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s).
A pace is a unit of length consisting either of one normal walking step (approximately 0.75 metres or 30 inches), or of a double step, returning to the same foot (approximately 1.5 metres or 60 inches). The normal pace length decreases with age and some health conditions. [1]
Humans spontaneously switch from a walk to a run as speed increases. In humans, the preferred transition speed from walking to running typically occurs around 2.0 m/s (7.2 km/h; 4.5 mph), although slight differences have been shown based on testing methodology. [1] [2] [3] [4]
“Walking for a mile at a moderate pace equals about 2,000 steps, and speed-walking at a slightly greater speed may work out to be a tad closer to 1.2 miles per 2,000 steps, so it’s not as vast ...
In Japan, the standard measure for walking speed is 80 m/min (4.8 km/h). Champion racewalkers can average more than 14 km/h (8.7 mph) over a distance of 20 km (12 mi). An average human child achieves independent walking ability at around 11 months old. [6]
Average walking speed—below a speed of about 2 m/s, it is more efficient to walk than to run, but above that speed, it is more efficient to run. 2.39: 8.53: 5.35: 7.97 × 10 −9: World record time 50m freestyle swim 5.78: 20.81: 12.93: 1.928 × 10 −8: World record time marathon [13] 6–7: 20–25: 12–15: 1.8–2.3 × 10 −8 ...
SI, and hence the use of "km/h" (or "km h −1 " or "km·h −1 ") has now been adopted around the world in many areas related to health and safety [36] and in metrology [37] in addition to the SI unit metres per second ("m/s", "m s −1 " or "m·s −1 "). SI is also the preferred system of measure in academia and in education.
