What does one fermi represent?

One fermi is a non-SI length unit representing 1 femtometre, mainly used to measure nuclear-scale distances.

What is the Bohr radius used for?

The Bohr radius is the atomic unit of length denoting the most probable electron-nucleus distance in hydrogen's ground state, used in quantum chemistry and atomic physics.

Why are conversion results so small?

Because fermi and Bohr radius measure very different length scales (femto- vs atomic scale), conversions produce very small numbers.
