A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 100 . [1] Equivalently, there are 100 centimetres in 1 metre. The centimetre was the base unit of length in the now deprecated ...
1–10 μm — diameter of a typical bacterium. 1.55 μm — wavelength of light used in optical fibre. 3–4 μm — size of a typical yeast cell. 5 μm — length of a typical human spermatozoon 's head [22] 6 μm — anthrax spore. 7 μm — diameter of the nucleus of a typical eukaryotic cell.
A US study published in 2015 of the stated preferences of a panel of 75 women using 3D-printed models as scale references showed a preferred penis length of 16 cm (6.3 in) and a preferred circumference of 12.2 cm (4.8 in) for long-term sexual partners, with slightly larger preferred sizes of a length of 16.3 cm (6.4 in) and circumference of 12. ...
The Egyptian equivalent of the foot—a measure of four palms or 16 digits—was known as the djeser and has been reconstructed as about 30 cm (11.8 in). The Greek foot (πούς, pous) had a length of 1 / 600 of a stadion, [12] one stadion being about 181.2 m (594 ft); [13] therefore a foot was, at the time, about 302 mm (11.9 in). Its ...
The giant huntsman spider is the largest member of the family Sparassidae, boasting a 30 cm (12 in) leg-span, and 4.6 cm (1.8 in) body-length. [2] The largest known member of the Sparassidae known prior to the discovery of H. maxima was the Australian Beregama aurea (L. Koch, 1875) with a body length of about 4 cm (1.6 in). [ 5 ] (
Shaku (Japanese: 尺) or Japanese foot[1][2] is a Japanese unit of length derived (but varying) from the Chinese chi, originally based upon the distance measured by a human hand from the tip of the thumb to the tip of the forefinger [3][a] (compare span). Traditionally, the length varied by location or use, but it is now standardized as 10/33 m ...
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.
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.
