Convert a.u. of length to ell
Please provide values below to convert a.u. of length [a.u., b] to ell [ell], or Convert ell to a.u. of length.
1 a.u., b = 4.6297e-11 ell. To convert a.u. of length to ell, multiply the value by 4.6297e-11; to go the other way, divide by it (1 ell = 21599568049.5 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 = 4.6297e-11 ell
- 1 ell = 21599568049.5 a.u., b
- 10 a.u., b = 4.6297e-10 ell
- 100 a.u., b = 4.62972221347e-09 ell
How to Convert A.u. Of Length to Ell
1 a.u., b = 4.62972221347332e-11 ell
Example: convert 15 a.u., b to ell:
15 a.u., b = 15 × 4.62972221347332e-11 ell = 6.94458332020997e-10 ell

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.
Ell
The ell is an obsolete unit of length, originally used for measuring cloth. Its length varied in different countries, but it was generally around 45 inches.
History/Origin
The word "ell" is derived from the Latin "ulna," meaning "forearm," as the unit was originally based on the length of the forearm.
Current Use
The ell is no longer in use.
Frequently Asked Questions
