Enter the physical length and the wavelength into the Calculator. The calculator will evaluate the Electrical Length. 

Electrical Length Formula

EL = PL / WL


  • EL is the Electrical Length ()
  • PL is the physical length
  • WL is the wavelength

To calculate Electrical Length, divide the physical length by the wavelength.

How to Calculate Electrical Length?

The following steps outline how to calculate the Electrical Length.

  1. First, determine the physical length. 
  2. Next, determine the wavelength. 
  3. Next, gather the formula from above = EL = PL / WL.
  4. Finally, calculate the Electrical 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.

physical length = 34

wavelength = 56
