What is a Planck length?

A Planck length is the fundamental theoretical length scale defined using constants in quantum gravity, indicating where classical space concepts may no longer apply.

Why convert Planck length to femtometers?

Converting to femtometers helps relate extremely small theoretical scales to experimentally relevant nuclear and subnuclear distances.

Is the Planck length used in experiments?

No, the Planck length is a theoretical scale, and experimental measurements typically use larger units like femtometers.
