Mean length from cervix to introitus: 6.3 cm (2.5 in). Mean width: at the proximal vagina: 3.3 cm (1.3 in); at the pelvic diaphragm: 2.7 cm (1.1 in); at the introitus: 2.6 cm (1.0 in) A 2006 U.S. study of vagina sizes using Magnetic Resonance Imaging (MRI) on 28 volunteers between 18 and 39 years old, with heights ranging from 1.5 to 1.7 metres ...
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Electronic calipers can measure diameter at breast height and send measured data via Bluetooth to a field computer. Tree trunks are measured at the height of an ...
The nanometre ( SI symbol: nm) is a unit of length in the metric system equal to 10−9 metres ( 1 1 000 000 000 m = 0.000 000 001 m ). To help compare different orders of magnitude, this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm). 1 nm – diameter of a carbon nanotube.
240 cm: 7 ft 10.5 in: Josef Drásal: Tallest man in what is today the Czech Republic; his height is also often listed as 242 cm (7 ft 11.5 in). 1841–1886 (45) Mongolia: 240 cm: 7 ft 10.5 in: Öndör Gongor: Very tall man in early-20th-century Mongolia. Was measured by Roy Chapman Andrews. 1880/85 – 1925/30 Bosnia and Herzegovina: 238 cm 7 ...
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere . In more modern usage, the length of a diameter is also called the diameter.
A circular milis a unitof area, equal to the area of a circlewith a diameterof one mil(one thousandth of an inch or 0.0254 mm). It corresponds to approximately 5.067×10−4 mm2. It is a unit intended for referring to the area of a wire with a circular cross section.
