What does one terameter represent?

One terameter is an SI-derived unit of length equal to one trillion metres, used to express very large distances like those between planets.

What is an atomic unit of length?

An atomic unit of length is the Bohr radius, representing the typical separation between an electron and proton in a hydrogen atom, widely used in atomic physics.

Why convert terameters to atomic units of length?

Converting helps relate astronomical distances to atomic-scale measurements, supporting research in fields linking atomic physics and astronomy.
