Weights and Measures
in Use in the ROC

The metric system is the official system of weights and measures in the ROC, and it is used for nearly all purposes. Certain things, however, continue to be measured according to various other systems. Real estate property, for example, is usually measured in p'ing (tsubo), or the size of a six-by-six-foot tatami mat, a remnant from Taiwan's period of Japanese occupation. There are measures for gold, Chinese herbal medicine, and other specialized commodities. The following tables give equivalents in the diverse systems in use in Taiwan: the Taiwan system, the metric system, and the English system.
