Convert Earth's equatorial radius to a.u. of length
Please provide values below to convert Earth's equatorial radius [R_e] to a.u. of length [a.u., b], or Convert a.u. of length to Earth's equatorial radius.
1 R_e = 1.2053e+17 a.u., b. To convert Earth's equatorial radius to a.u. of length, multiply the value by 1.2053e+17; to go the other way, divide by it (1 a.u., b = 8.2967e-18 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
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.
