Taiwanese units of measurement
Taiwanese units of measurement (Chinese: 臺制; pinyin: Táizhì; Pe̍h-ōe-jī: Tâi-chè) are the customary and traditional units of measure used in Taiwan. Many of the units derive from Japanese units of measurement and have similar names as Chinese units of measurement but different conversions than in mainland China or Hong Kong. In some cases these units are used exclusively, in some cases alongside official metric (SI) units, and in other cases they have been supplanted by metric units. Linguistically, practically all Taiwanese units of measure are Chinese classifiers used to classify nouns.
Linear measure in Taiwan is largely metric but some units derived from traditional Japanese units of measurement remain in use.
Unlike with other measures, area continues to be almost commonly measured with traditional units. Taiwanese units of land measurement derive from both traditional Dutch and Japanese measurements. The principal unit of land measure, the jiǎ (Chinese: ; Pe̍h-ōe-jī: kah), derives from the obsolete Dutch unit morgen which was introduced during Taiwan's Dutch era; or from the Dutch word for "field", . The lí (; lê) represented the area that could be farmed by one man with one ox and one plow in one day. The principal unit for measuring the floorspace of an office or apartment, the píng (; pêⁿ / pîⁿ / phêⁿ / phîⁿ / phiâⁿ / phêng) derives from the tsubo (Japanese: ?), and is the size of two sleeping (tatami) mats.
