The Wikipedia has the following information about this codepoint:
Chinese units of measurement (Chinese: 市制; pinyin: shìzhì; literally: "market system") are the customary and traditional units of measure used in China. In the People's Republic of China, the units were re-standardised during the late 20th century to make them approximate SI (metric) units. Many of the units were formerly based on the number 16 instead of 10. In Hong Kong, the British Imperial system was used together with Hong Kong units of measurement, which were traditional Chinese weights and measures, and now traditional Chinese units and Imperial units are used alongside the metric system, which was introduced by legislation in 1976 as the official standard system of weights and measures. Taiwanese units of measurement, which appeared under the colonial influences of the Dutch and the Japanese, for the most part may have similar names but are different from the Chinese units of measurement. Taiwan is now fully metricated.
The Chinese name for most SI units is based on that of the closest traditional unit. When it is necessary to emphasize which system is used, the words "market" (市 shì) for traditional units or "common/standard" (公 gōng) for SI units may be added in front of the name. SI is the official system of units, but traditional units are still ubiquitously used in everyday life.
Note: The names lí (厘) and fēn (分) for small units are the same for length, area, and mass; however, they refer to different kinds of measurements.
