Enter the frequency and inductance into the calculator to determine the inductive reactance. This calculator can also evaluate any of the variables given the others are known.

Inductance To Ohms Formula

The following formula is used to calculate the inductive reactance, or ohms, from inductance.

X_L = 2πfL


  • X_L is the inductive reactance (Ohms)
  • f is the frequency (Hz)
  • L is the inductance (H)

To calculate the inductive reactance, multiply the frequency by the inductance, then multiply the result by 2π. The result is the inductive reactance in ohms, which represents the opposition that an inductor presents to alternating current.

What is Inductance To Ohms?

Inductance to ohms is a conversion that relates to electrical circuits. Inductance, measured in henries (H), is a property of an electrical circuit that opposes a change in the electric current. Ohms, on the other hand, is a unit of electrical resistance, which measures how much a device or material reduces the electric current flow through it. The relationship between these two can be described using Ohm’s law and the formula for inductive reactance, which is the opposition that an inductor presents to alternating current, calculated as 2πfL, where f is the frequency and L is the inductance.

How to Calculate Inductance To Ohms?

The following steps outline how to calculate the Inductance To Ohms using the formula X_L = 2πfL.

  1. First, determine the frequency (f) in Hertz (Hz).
  2. Next, determine the inductance (L) in Henrys (H).
  3. Next, gather the formula from above = X_L = 2πfL.
  4. Finally, calculate the Inductive Reactance (X_L) in Ohms (Ω).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
