How to Convert Bohr Radius to Meter
1 a.u. = 5.29177210903e-11 m
Example: convert 15 a.u. to m:
15 a.u. = 15 × 5.29177210903e-11 m = 7.937658163545e-10 m

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.
Meter
The meter is the base unit of length in the International System of Units (SI). It is the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
History/Origin
The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the international prototype meter was established as the length of a prototype meter bar, made of an alloy of platinum and iridium. In 1960, the meter was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86.
Current Use
The meter is used worldwide in many applications such as science, engineering, and trade. The United States is one of the few countries in which the meter is not widely used in everyday life and trade.
