What is a gigameter used to measure?

A gigameter is used to express very large distances such as those found in interplanetary space, including spacecraft trajectories and distances between planets.

Why convert gigameters to atomic units of length?

Converting to atomic units allows linking large astronomical scales to atomic-scale physics, simplifying calculations and theoretical modeling in quantum mechanics.

Are gigameters and atomic units directly comparable?

While they measure length, they represent vastly different scales, with gigameters suited for astronomical distances and atomic units for sub-nanometer atomic dimensions.
