# ››Definition: Gigaohm

The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.

So 1 gigaohm = 109 ohms.

The definition of a ohm is as follows:

The ohm (symbol: Ω) is the SI unit of electrical impedance or, in the direct current case, electrical resistance, named after Georg Ohm. It is defined as the resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.
