'abohm' originates from the combination of the prefix 'ab-' meaning 'away from' and 'ohm,' the unit of electrical resistance named after Georg Simon Ohm.

'abohm' was derived from the CGS system of units, which was widely used in scientific contexts before the adoption of the International System of Units (SI).

Initially, it was used to measure very small resistances in scientific experiments, and this meaning has remained consistent.
