U+540B "吋" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
吋
U+540B "吋" CJK Unified Ideograph-# is a Chinese character that functions as a unit of measurement, specifically representing an inch, though it also historically corresponds to the British or metric unit known as the "cun" or "tsun," a traditional Chinese inch roughly equivalent to 3.33 centimeters. In modern usage, it appears in contexts involving dimensions, such as screen sizes or lengths, and is composed of the radical "口" (mouth) combined with the phonetic component "寸" (cun), which itself denotes a unit of length. This character is encoded in the CJK (Chinese, Japanese, Korean) Unified Ideographs block, reflecting its shared use across East Asian writing systems where it may carry similar meanings related to measurement.
