Convert a.u. of length to exameter
Please provide values below to convert a.u. of length [a.u., b] to exameter [Em], or Convert exameter to a.u. of length.
1 a.u., b = 5.2918e-29 Em. To convert a.u. of length to exameter, multiply the value by 5.2918e-29; to go the other way, divide by it (1 Em = 1.8897e+28 a.u., b). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 a.u., b = 5.2918e-29 Em
- 1 Em = 1.8897e+28 a.u., b
- 10 a.u., b = 5.2918e-28 Em
- 100 a.u., b = 5.2918e-27 Em
How to Convert A.u. Of Length to Exameter
1 a.u., b = 5.29177249e-29 Em
Example: convert 15 a.u., b to Em:
15 a.u., b = 15 × 5.29177249e-29 Em = 7.937658735e-28 Em

A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is 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 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
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.
Frequently Asked Questions
