Convert exameter to Bohr radius
Enter a value below to convert exameter [Em] to Bohr radius [a.u.]. Reverse conversion: Convert Bohr radius to exameter.
1 Em = 1.8897e+28 a.u.. To convert exameter to Bohr radius, multiply the value by 1.8897e+28; to go the other way, divide by it (1 a.u. = 5.2918e-29 Em). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Exameter: Definition and Use
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: Definition and Use
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.
