台尺與英尺

Taiwanese Meter and British Foot

台尺與英尺是「量」相接近，但實際上不同的兩個長度單位。這兩個量分屬兩個系統，為何如此接近，是否其間有因緣關係，尚待考證。本文介紹此兩單位與公制間之轉換，並就網際網路上相關描述之現象舉例描述理解上之出入。面積與體積單位為由長度導出，本文亦就相關之「坪」、「材」略予說明。而台灣地區另一常用面積單位「甲」，則有不同淵源，與台尺無關。 The actual length of Taiwanese meter is very close to British foot. But, these twomeasurement units originated from different cultures. This note describes the conversion of bothTaiwanese meter and British foot to the metric meter. Some commonly used units for area andvolume in Taiwan are also discussed. The units for area and volume are based on the length units.The area unit “ping” and volume unit “cai”, derived from Taiwanese meter are briefly introduced.Meanwhile, another area unit “jia” originated from different source.
