Capacitive reactance is a measure of a capacitor's opposition to alternating current (AC) and is calculated using the formula (X_C = \frac{1}{2\pi fC}), where (X_C) is the capacitive reactance, (f) is the frequency of the AC signal, and (C) is the capacitance in farads. The unit used to express this opposition to current flow is ohms, which is the standard unit of resistance in electrical systems.

Ohms serve as a common reference for both resistance and reactance, which allows for the comparison of how different components affect the flow of electricity in a circuit. Despite capacitive reactance being linked to capacitance (measured in farads) and the frequency of the AC signal, it is categorized under the same measurement standard as resistive opposition.

Therefore, measuring capacitive reactance in ohms is consistent with how electrical components are evaluated in terms of their ability to impede current flow.
