About these units
Cun (Chinese) (cun)
The Chinese inch, 1/30 m (about 3.33 cm) in the modern market system. Also used in acupuncture, where a 'body cun' is proportional to the patient.
Hand anatomy gave the cun its role. The traditional definition is the width of a person's thumb at the knuckle, and the unit is commonly translated as the Chinese inch. That human scale is the reason acupuncture still uses a body cun, which is proportional to the patient and is not a fixed number of millimeters. Two forefingers side by side are counted as 1.5 cun, and four fingers together as 3 cun.
As a measure of ordinary objects, the cun is one tenth of a chi and ten times a fen. Under the modern market system it equals 10/3 centimeters, roughly 3.33 cm. Hong Kong kept a British-influenced standard in which the cun is about 3.715 cm, and Japan's related sun is about 3.03 cm, so the same character covers several different sizes in different places. The phrase chi cun, literally foot and inch, also became the everyday Chinese word for dimensions.
1 cun (Chinese) = 0.03333333333 meters (approximately).

Foot (ft)
12 inches. Defined as exactly 0.3048 meters. Still the standard unit for height, altitude in aviation and room dimensions in the US and UK.
Human anatomy supplied the idea: an adult foot is roughly 15 percent of body height. Ancient cultures turned that into standards, but not the same one. The Greek pous was about 302 mm, the standard Roman pes about 295.7 mm, and a Harappan foot of about 335 mm has been reported from the Indus Valley. Historically, a foot fell somewhere between about 250 and 335 mm. Charlemagne tried to standardize units around 790 with little lasting success, and in 1593 English law fixed the statute mile at 5,280 feet.
The modern foot dates from the 1959 International Yard and Pound Agreement, which defined the yard as exactly 0.9144 meter and so the foot as exactly 0.3048 meter; the UK adopted it on 1 January 1964. The US survey foot, defined in 1893 as 1200/3937 meter, was deprecated on 31 December 2022. Feet remain in everyday use for height and rooms in the US, and ISO shipping containers are defined in them. Aviation altitudes use them too: flight level 330 means 33,000 feet.
1 foot = 0.3048 meters (exactly).
