Convert chain (US survey) to Bohr radius
Please provide values below to convert chain (US survey) [ch (US)] to Bohr radius [a.u.], or Convert Bohr radius to chain (US survey).
1 ch (US) = 380153185345 a.u.. To convert chain (US survey) to Bohr radius, multiply the value by 380153185345; to go the other way, divide by it (1 a.u. = 2.6305e-12 ch (US)). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Chain (Us Survey)
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey chain was used for land surveying in the United States.
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.
