What is the Planck length used for?

The Planck length sets a natural scale in quantum gravity and is used in theoretical physics for high-energy calculations and thought experiments about spacetime and measurement limits.

Why use terameters for length?

Terameters represent very large distances in astronomy, such as interplanetary distances and planetary orbit sizes, providing context for cosmic scale measurements.

Can I use this conversion for everyday measurements?

No, the conversion is primarily useful for conceptual understanding in physics and astronomy due to the tremendous scale difference.
