0.001pm

That's 1.19× as long as a proton, while a gold nucleus is 7.3× longer.

What it means

How small is that?

Atoms have no sharp edge; radii depend on how they are measured (covalent, van der Waals, ionic).

The math

How to convert fm to pm

To convert femtometers (fermi) to picometers, multiply by 0.001.

Example: 1 fm × 0.001 = 0.001 pm.

In the other direction, 1 pm = 1,000 fm.
