Please provide values below to convert a.u. of length [a.u., b] to hectometer [hm], or Convert hectometer to a.u. of length.
How to Convert A.u. Of Length to Hectometer
1 a.u., b = 5.29177249e-13 hm
Example: convert 15 a.u., b to hm:
15 a.u., b = 15 × 5.29177249e-13 hm = 7.937658735e-12 hm

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.
Hectometer
A hectometer is a unit of length in the metric system equal to 100 meters.
History/Origin
The prefix "hecto-" from the Greek "hekaton" meaning hundred, was part of the original metric system adopted in France in 1795.
Current Use
The hectometer is not a widely used unit of length in English-speaking countries. It is sometimes used in surveying and for marking distances on highways in some countries.
