What is the Planck length used for?

It serves as a natural length scale in quantum gravity and theoretical physics, helping define Planck units and understanding quantum spacetime effects.

Why convert Planck length to Earth's equatorial radius?

This conversion helps relate extremely small quantum length scales to familiar planetary distances to improve comprehension of scale differences.

Is the Earth's equatorial radius constant?

Its value is based on geodetic reference models like WGS84 and may vary slightly depending on the chosen model.
