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

Ohms To Henries Formula

The following formula is used to calculate the conversion from Ohms to Henries.

H = R / (2 * π * f)


  • H is the inductance in Henries (H)
  • R is the resistance in Ohms (Ω)
  • f is the frequency in Hertz (Hz)
  • π is the mathematical constant Pi (~3.14159)

To calculate the inductance in Henries, divide the resistance in Ohms by the product of 2, Pi, and the frequency in Hertz. This formula is derived from the relationship between resistance, inductance, and frequency in an electrical circuit.

What is a Ohms To Henries?

Ohms to Henries is a conversion factor used in electrical engineering to convert the unit of electrical resistance (Ohms) to the unit of electrical inductance (Henries). This conversion is typically used in the analysis and design of electrical circuits and systems. It’s important to note that this conversion requires additional parameters such as frequency because Ohms and Henries measure different electrical properties.

How to Calculate Ohms To Henries?

The following steps outline how to calculate the Ohms To Henries.

  1. First, determine the resistance in Ohms (R).
  2. Next, determine the frequency in Hertz (f).
  3. Next, gather the formula from above = H = R / (2 * π * f).
  4. Finally, calculate the inductance in Henries (H).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
