 Context examples 

A measurement in ohms is the reciprocal of a measurement in siemens.

(Ohm, NCI Thesaurus)

A unit of electrical, mechanical, and thermal energy (as well as work and quantity of heat) in the SI system, equal to the work done when the point of application of a force of one newton is displaced through a distance of one meter in the direction of the force or the work done when a current of one ampere passes through a resistance of one ohm for one second.

(Joule, NCI Thesaurus)

Ohm is also used to measure impedance and reactance for complex resistance.
