What is the meter unit used for?

The meter is the SI base unit of length used to quantify linear distance in scientific, engineering, and everyday contexts such as construction and surveying.

What does the atomic unit of length represent?

It represents the Bohr radius, the characteristic length scale in atomic physics corresponding to the average electron–proton separation in hydrogen's ground state.

Why does converting meters to a.u. result in very large numbers?

Because the atomic unit of length is extremely small, converting macroscopic lengths in meters yields very large numerical values.
