Which unit is used to measure inductive reactance?

Explanation:
Inductive reactance is a part of impedance that opposes AC current due to an inductor. Its value is X_L = ωL = 2πfL, which ends up in the same unit as impedance: ohms. The ohm is voltage per current, so it correctly represents how strongly the circuit resists current flow at a given frequency. Henry is the unit of inductance, not reactance; volts measure voltage, and amps measure current. So the appropriate unit for inductive reactance is ohms.
