The length of full hematological adaptation can be approximated by multiplying the altitude in kilometres by 11.4 days. For example, to adapt to 4,000 metres (13,000 ft) of altitude would require 45.6 days. [27] The upper altitude limit of this linear relationship has not been fully established. [6] [16]
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
For instance, one survey shows there is 10.8 centimetres (4.3 in) gap between the tallest state and the shortest state in Germany. [6] Under such circumstances, the mean height may not represent the total population unless sample subjects are appropriately taken from all regions with using weighted average of the different regional groups.
1.6 × 10 −5 quectometers (1.6 × 10 −35 meters) – the Planck length (Measures of distance shorter than this do not make physical sense, according to current theories of physics.) 1 qm – 1 quectometer, the smallest named subdivision of the meter in the SI base unit of length, one nonillionth of a meter.
From the time of Magellan's expeditions until the end of the 18th century, European explorers reported about the Patagonians 2.7 and 3.0 m (9 and 10 ft) tall, and even an individual about 4 or 4.5 m (13 or 15 ft) tall captured by Magellan's crewmen near the Santa Cruz River (Argentina). [192]

The official distance became 300 meters, but many competitions continued to be in yards because the tracks were still marked for that distance. Hurdle heights also have undergone a period of evolution. Until 1984, boys ran over low hurdles 30" in height. When girls were introduced to the event around 1981, they ran the same height as the boys ...
