Ancient book conversion

Is it more than three meters high for any ancient people? In fact, it is only 1.8 meters high today, which can only be converted into half of today's "feet and inches". "Historical Records of Yu Benji" said that Dayu set himself ten feet and took one tenth of it as the ruler, so people were called "husbands". In fact, Xiachi is only 4 inches and 8 minutes of today's city scale, and Dayu is only 4 feet and 8 minutes, only 1.60 meters high. According to various ancient books, experts calculated the length of one foot in the past dynasties: one foot in the Warring States period was 22.5 cm; 23.1cm in Han dynasty; Three kingdoms 24cm；; Gold 24.5cm；; Southern and Northern Dynasties 24.2-29.6 cm; Sui 29.6cm；; Tang 30 cm; Song 31.2cm; 32 cm in Ming and Qing dynasties.
