U+00B5 "µ" Micro Sign Unicode Character
U+00B5 "µ" Micro Sign is a typographical symbol representing the SI prefix micro, meaning one millionth (10⁻⁶), and is visually identical to the Greek letter mu (μ). It is widely used in scientific and engineering contexts, particularly in measurements of length (micrometers), mass (micrograms), and time (microseconds), as well as in chemistry and biology for notations like µg (microgram) or µL (microliter). Despite its visual similarity to the Greek mu, it is encoded as a distinct character to ensure consistent representation in digital text across different systems and applications. This character is part of the C1 Controls and Latin-1 Supplement block and is commonly found in technical documents, spreadsheets, and programming environments where precise unit notation is required.
