Bohr radii to ångströms
Type a value in a₀ to get it in Å instantly.
0.5292Å
That's about the same as a hydrogen atom (Bohr radius).
Convert the other way: Å to a₀
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 a₀ to Å
To convert Bohr radii to ångströms, multiply by 0.529177.
Example: 1 a₀ × 0.529177 = 0.529177 Å.
In the other direction, 1 Å = 1.88973 a₀.
