How many centimeters is 6 inches?

Because 1 m = 100 cm, 1 ft = 10 in, so 1 m =3 ft, we can deduce that 100 cm =30 in.

Because 30÷6=5, 6 inches is one fifth of 30 inches, that is, one fifth of 100 cm, so 6 inches = 100÷5 cm =20 cm.

Origin of inch

Cunyue was born in the Warring States period, and its glyph is to add a short horizontal at the bottom of the word "you"; It means that there is a short cross at the radial artery one inch away from the palm root, which indicates this part, and it is the place for pulse diagnosis in traditional Chinese medicine. This place is Cunkou, which is called Cunkou (Chinese medicine has the theory of Cunkou, Guankou and ruler for pulse diagnosis), and it is also called Pulse Gate, which is about an inch away from the palm root and is the name of the meridian part.

The length unit inch was determined by the ancients according to this distance, and some people think that the length of inch is only the length of the middle finger joint. Xiao Zhuan basically follows the Warring States script. In the Li period, its structure, stroke shape, stroke order and strokes were adjusted many times, indicating that the symbols of things were either abrupt or uplifting, or horizontal and vertical, with regular script as the symbol. According to the calculation of the ancients, ten points is one inch, which existed as a unit of measurement in ancient Chinese.
