Convert a.u. of length to chain
Please provide values below to convert a.u. of length [a.u., b] to chain [ch], or Convert chain to a.u. of length.
1 a.u., b = 2.6305e-12 ch. To convert a.u. of length to chain, multiply the value by 2.6305e-12; to go the other way, divide by it (1 ch = 380152397670 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 = 2.6305e-12 ch
- 1 ch = 380152397670 a.u., b
- 10 a.u., b = 2.6305e-11 ch
- 100 a.u., b = 2.6305e-10 ch
How to Convert A.u. Of Length to Chain
1 a.u., b = 2.63052398492802e-12 ch
Example: convert 15 a.u., b to ch:
15 a.u., b = 15 × 2.63052398492802e-12 ch = 3.94578597739203e-11 ch

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.
Chain
A chain is a unit of length equal to 66 feet, or 22 yards.
History/Origin
The chain was developed by English surveyor Edmund Gunter in the early 17th century. It was designed to be a convenient length for surveying land.
Current Use
The chain is still used in some surveying applications and is the length of a cricket pitch.
Frequently Asked Questions
What is 1 a.u. of length in chain?
