Its capital Ω is the ohm, the unit of electrical resistance, and also marks solid angle and the sample space in probability. ω is the lowercase form of Omega, letter 24 of 24 in the Greek alphabet (pronounced oh-MAY-ga). Its capital counterpart is Ω. In science and maths it is used for: Ohm and solid angle (Ω), angular frequency (ω).
