Exameter To Cable Length (Em To Cable) Converter

The Exameter To Cable Length (Em To Cable) Converter is a handy tool designed to help you determine the length of a cable based on measurements taken in Exameters (Em). This is especially useful in telecommunications, electrical installations, and testing scenarios where precise cable length calculations are needed.

An Exameter (Em) is a unit of measurement used to quantify the electrical length of a cable based on the time it takes for an electrical signal to travel through it. It is related to the physical length of the cable and the velocity factor of the cable material.

The basic formula to convert Exameters to cable length is:
Cable Length (meters) = Em × Velocity Factor

Here, the Velocity Factor (VF) is a decimal value that represents the speed at which the electrical signal travels through the cable relative to the speed of light in a vacuum. For most cables, the VF ranges between 0.66 and 0.85, depending on the cable type.

To use this converter, simply input the measured value in Exameters and select or input the appropriate velocity factor for your cable. The tool will then automatically calculate the corresponding cable length in meters, providing an easy way to estimate cable lengths from electrical measurements.
