Convert Bohr radius to chain
Please provide values below to convert Bohr radius [a.u.] to chain [ch], or Convert chain to Bohr radius.
1 a.u. = 2.6305e-12 ch. To convert Bohr radius to chain, multiply the value by 2.6305e-12; to go the other way, divide by it (1 ch = 380152425039 a.u.). 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. = 2.6305e-12 ch
- 1 ch = 380152425039 a.u.
- 10 a.u. = 2.6305e-11 ch
- 100 a.u. = 2.6305e-10 ch
How to Convert Bohr Radius to Chain
1 a.u. = 2.63052379554899e-12 ch
Example: convert 15 a.u. to ch:
15 a.u. = 15 × 2.63052379554899e-12 ch = 3.94578569332349e-11 ch

Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, 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. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used 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.
