Convert angstrom to Earth's equatorial radius
Please provide values below to convert angstrom [A] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to angstrom.
How to Convert Angstrom to Earth's Equatorial Radius
1 A = 1.5678559428874e-17 R_e
Example: convert 15 A to R_e:
15 A = 15 × 1.5678559428874e-17 R_e = 2.3517839143311e-16 R_e
Angstrom to Earth's Equatorial Radius Conversion Table
| angstrom | Earth's equatorial radius |

Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
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.
