About the Omega Symbol
Ω Omega is the 24th and final letter of the Greek alphabet, giving it profound symbolic weight across science, religion, and culture. Its name means “great O” (from ō mega), distinguishing it from omicron (“little O”). In the Christian tradition Omega pairs with Alpha (ΑΩ) as the phrase “the beginning and the end.” In physics and engineering the capital Ω (U+03A9) is universally used as the symbol for Ohm — the SI unit of electrical resistance — making it one of the most recognised scientific symbols on Earth. The lowercase ω (U+03C9) represents angular frequency (radians per second) in mechanics and signal processing, and is also the symbol for the first infinite ordinal number in set theory. In cosmology Ω denotes the density parameter of the universe. In music theory ω sometimes denotes a diminished-seventh chord. The dedicated Ohm sign Ω (U+2126) is a legacy encoding that canonically decomposes to Ω. In HTML use Ω or Ω for capital omega, and ω or ω for lowercase.
