History, typographic usage standards, and Unicode block
Omega (Ω, U+03A9) is the last letter of the Greek alphabet, used in physics for electrical resistance (ohms) and in probability for the full sample space. On Mac, Option+Z types it directly.
In standard typography and document styling, symbols and accents should adhere to standard spacing guidelines. When typing numbers or equations, avoid confusing lookalike characters (such as confusing the letter "x" with the true multiplication operator "×", or using a degree symbol "°" in place of a superscript zero "⁰").
Official Unicode Reference:
Registered as GREEK CAPITAL LETTER OMEGA at codepoint U+03A9 within the Unicode Standard. Consult the official Unicode Greek and Coptic specification chart (PDF via unicode.org).

Common questions about typing and formatting Omega Symbol

Why does Ω not appear when I press the keys?

Do I need a Greek keyboard layout to type Ω?
No. Omega Symbol is available through an Alt code, a Mac shortcut, Word's Alt+X conversion and the Symbol dialog, all without switching layout. A Greek layout is only worth adding if you type continuous Greek text rather than the occasional symbol.
