U+03C9 "ω" Greek Small Letter Omega Unicode Character

U+03C9 "ω" Greek Small Letter Omega is the twenty-fourth and final letter of the Greek alphabet, historically representing a long "o" sound and serving as the direct ancestor of the Latin letter "O" and the Cyrillic letter "О". In modern Greek, it is pronounced as a close-mid back rounded vowel, similar to the "o" in the English word "boat". Beyond its linguistic role, omega holds significant cultural and scientific importance: it is widely used as a symbol in physics and mathematics to denote angular velocity, the ohm unit of electrical resistance (in uppercase Omega "Ω"), and the last or ultimate position in a series, as in the phrase "Alpha and Omega" signifying the beginning and the end.
