“µ” U+00B5: Micro Sign

ℹ️ About

The Micro Sign (µ) is a technical character representing the SI prefix “micro,” equal to one-millionth ($10^{-6}$). While visually identical to the Greek lowercase letter Mu ($\mu$), it is encoded separately in the Latin-1 Supplement block to maintain compatibility with legacy ISO/IEC 8859-1 systems. It is used extensively in science for units like micrometers (µm) and microfarads (µF).
