Enter the total inductance (H) and the total length into the Calculator. The calculator will evaluate the Inductance Per Unit Length. 

Inductance Per Unit Length Formula

IPL = I / L


  • IPL is the Inductance Per Unit Length (H/unit length)
  • I is the total inductance (H)
  • L is the total length

To calculate Inductance Per Unit Length, divide the total inductance by the total length.

How to Calculate Inductance Per Unit Length?

The following steps outline how to calculate the Inductance Per Unit Length.

  1. First, determine the total inductance (H). 
  2. Next, determine the total length. 
  3. Next, gather the formula from above = IPL = I / L.
  4. Finally, calculate the Inductance Per Unit Length.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total inductance (H) = 400

total length = 20
