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.

Omega Symbol Upside Down

Omega already has a kind of curved shape, but if you’re after an upside-down look, here’s what people use:

That’s called the Inverted Ohm Symbol—rarely used but it exists.

Omega Symbol W Meaning

Some search “omega symbol w” because Ω kind of looks like a W. But they’re not the same. Omega has curves at the ends, W is sharper.

Omega Symbol in Physics Formulas

Angular Velocity:

\omega = \frac{\theta}{t}

Where:

  • ω = angular velocity
  • θ = angular displacement
  • t = time

Harmonic Motion:

x = A\sin(\omega t)

Used in oscillation and wave mechanics.
