Source: Browser Default
U+33D9 "㏙" Square Ppm is an ideographic symbol that represents the abbreviation for "parts per million," a dimensionless unit of measurement often used in chemistry, environmental science, and engineering to denote very dilute concentrations of one substance within another. Encoded in the CJK Compatibility block of Unicode, this character is designed for compatibility with East Asian text encodings where such shorthand notations appear in contexts like chemical formulas or labeling. It forms its composition by enclosing the letters "ppm" within a square layout, mimicking the typical appearance of a single East Asian character for streamlined typography in vertical or horizontal writing systems.
