Traditionally, the actual length of the shaku varied over time, location, and use. By the early 19th century, the shaku was largely within the range of 0.30175 to 0.303 meters (11.880 in to 11.929 in), [1] but a longer value of the shaku (also known as the kōrai-shaku) was also known, and was 1.17 times longer than the present value (35.5 centimeters or 14.0 inches).
Human height. 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. [4][5] In the early ...
0.3048 m. 30.48 cm. 304.8 mm. The foot (standard symbol: ft) [1][2] is a unit of length in the British imperial and United States customary systems of measurement. The prime symbol, ′, is commonly used to represent the foot. [3] In both customary and imperial units, one foot comprises 12 inches, and one yard comprises three feet.
The traditional units are still used for construction materials in Japan. For example, plywood is usually manufactured in 182 cm × 91 cm (about 72 in × 36 in) sheets known in the trade as saburokuhan (3 × 6版), or 3 × 6 shaku. Each sheet is about the size of one tatami mat. The thicknesses of the sheets, however, are usually measured in ...
The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.
One metre is exactly equivalent to 5 000 / 127 inches and to 1 250 / 1 143 yards. A simple mnemonic to assist with conversion is "three 3s": 1 metre is nearly equivalent to 3 feet 3 + 3 ⁄ 8 inches. This gives an overestimate of 0.125 mm. The ancient Egyptian cubit was about 0.5 m (surviving rods are 523–529 mm). [154]
These lengths typically ranged from 44.4 to 52.92 cm (1 ft 5 + 1 ⁄ 2 in to 1 ft 8 + 13 ⁄ 16 in), with an ancient Roman cubit being as long as 120 cm (3 ft 11 in). Cubits of various lengths were employed in many parts of the world in antiquity , during the Middle Ages and as recently as early modern times .
According to the Guinness World Records, the tallest human in recorded history was Robert Wadlow of the United States (1918–1940), who was 272 cm (8 ft 11 in). He received media attention in 1939 when he was measured to be the tallest man in the world, After reaching a height of 267 cm (8 ft 9 in). There are reports about even taller people ...
