Angstroms to nanometres
One angstrom is 0.1 nanometres. Atomic diameters and chemical bond lengths mostly fall between one and three angstroms, which is why crystallography and spectroscopy leaned on it.

Common values
Formula
nm = Å × 0.1
It is not an SI unit, so journals prefer nanometres or picometres. Check which one a figure is quoting.
Frequently asked questions
Q. How many nm is 1 Å?
1 Å is 0.1 nm, and 10 Å is 1 nm. Type any value in the box above to convert instantly.
Q. And how many Å is 1 nm?
1 nm is 10 Å. This converter works both ways, so typing in the right box updates the left one.
Q. Where is this unit used?
