About the Ohm Symbol
The ohm symbol (Ω) is the uppercase Greek letter Omega used as the SI unit of electrical resistance, named after physicist Georg Simon Ohm. One ohm is defined as the resistance that produces a potential difference of one volt when a current of one ampere flows through it, expressed by Ohm’s Law: V = IR. Component values are written as 10Ω (ten ohms), 4.7kΩ (4,700 ohms), or 2MΩ (two megaohms). Unicode provides two codepoints: the dedicated Ohm Sign (U+2126) and the Greek capital omega (U+03A9) — they are canonically equivalent and look identical. The inverted ohm sign (℧, U+2127), also called the mho, represents siemens (S), the unit of electrical conductance (the reciprocal of resistance). The lowercase omega (ω, U+03C9) denotes angular frequency (ω = 2πf) in electronics and physics. Use Ω or Ω to embed the ohm symbol in HTML.
