A random person in ancient times was 1.2 meters tall. Could it be that he was more than three meters tall? In fact, he was only 1.8 meters tall today, which is almost half of today's "foot and inch"
, Where do you measure less than three inches?
, "Historical Records·Yu Benji" said that Dayu determined himself to be one foot, and one-tenth of it was used as a foot, so men were called "husbands" . The Xia ruler was actually only 4 feet and 8 minutes of today's market ruler, while Dayu was only 4 feet and 8 inches, and only 1.60 meters tall.
Relevant experts have calculated the length of a foot in the past dynasties based on various ancient books: the Warring States period is 22.5 centimeters; the Han Dynasty is 23.1 centimeters; the Three Kingdoms is 24 centimeters; the Jin Dynasty is 24.5 centimeters; and the Southern and Northern Dynasties are 24.2-29.6 centimeters. cm; Sui 29.6 cm; Tang 30 cm; Song 31.2 cm; Ming and Qing 32 cm
Obviously, according to the system after the Tang Dynasty, the height of a seven-foot man will reach 2 meters Above, this is unlikely~~But according to the system before the Northern and Southern Dynasties, the so-called seven-foot man was only about 1.7 meters, which is almost the same as the average height of people today~~So, the height of a seven-foot man should be 1.7 About meters~~
By the way, Chinese history has always been based on the decimal system, but in the Zhou Dynasty, "8 inches is a ruler, 10 feet is a zhang, and a person is 11 feet tall, so he is called a husband"~~
