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.


Megameter

A megameter is a unit of length in the metric system equal to 10^6 meters.

History/Origin

The prefix "mega-" for 10^6 was adopted by the CGPM (General Conference on Weights and Measures) in 1873.

Current Use

The megameter is sometimes used to specify the diameters of planets and the distances of satellites.
