What does the classical electron radius represent?

It is a derived length scale representing the distance where classical electrostatic energy equals electron rest energy, used in particle and radiation physics.

What was the Roman actus used for?

The Roman actus was an ancient Roman unit of length used in land surveying, defining distances and field boundaries.

Is this conversion practical for everyday use?

No, due to the huge difference in scale, it is mainly useful for theoretical, historical, or educational comparisons.
