The abohm (symbol: abΩ) is the CGS-EMU unit of electrical resistance. One abohm equals 10⁻⁹ ohms (1 nanoohm). It is used in electromagnetic CGS unit systems.

The ohm (symbol: Ω) is the SI unit of electrical resistance. A conductor has a resistance of one ohm when a potential difference of one volt produces a current of one ampere. Named after Georg Simon Ohm, who formulated Ohm's law.
