Convert kilometer to Bohr radius
Please provide values below to convert kilometer [km] to Bohr radius [a.u.], or Convert Bohr radius to kilometer.
1 km = 1.8897e+13 a.u.. To convert kilometer to Bohr radius, multiply the value by 1.8897e+13; to go the other way, divide by it (1 a.u. = 5.2918e-14 km). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 km = 1.8897e+13 a.u.
- 1 a.u. = 5.2918e-14 km
- 10 km = 1.8897e+14 a.u.
- 100 km = 1.8897e+15 a.u.
How to Convert Kilometer to Bohr Radius
1 km = 18897261246257.7 a.u.
Example: convert 15 km to a.u.:
15 km = 15 × 18897261246257.7 a.u. = 283458918693866 a.u.

Kilometer
A kilometer is a unit of length in the metric system, equal to one thousand meters.
History/Origin
The term "kilometer" is derived from the Greek words "khilioi" (thousand) and "metron" (measure). The kilometer was first defined as part of the metric system in France in 1795.
Current Use
The kilometer is the most widely used unit of distance for road signs and travel distances in the world, with the notable exceptions of the United States and the United Kingdom.
Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
