How to Convert Exameter to Bohr Radius
1 Em = 1.88972612462577e+28 a.u.
Example: convert 15 Em to a.u.:
15 Em = 15 × 1.88972612462577e+28 a.u. = 2.83458918693866e+29 a.u.

Exameter
An exameter is a unit of length in the metric system equal to 10^18 meters.
History/Origin
The prefix "exa-" for 10^18 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The exameter is used in astronomy to measure the vast distances between galaxies.
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.
