U+334C "㍌" Square Megaton Unicode Character
Unicode Version 17.0
㍌
U+334C "㍌" Square Megaton is a precomposed CJK (Chinese, Japanese, and Korean) character known as a "square" form, specifically representing the unit "megaton." It is encoded in the CJK Compatibility block of Unicode, where it was designed to fit within a single character width for East Asian typography, rather than requiring separate characters for "mega" and "ton." This symbol denotes a unit of explosive energy equivalent to one million tons of TNT, often used in scientific or historical contexts to describe the yield of nuclear weapons. Its inclusion in Unicode facilitates digital text representation in languages like Japanese, where such squaring of units is a conventional typographic practice.
