Please provide values below to convert angstrom [A] to Earth's polar radius [R_p], or Convert Earth's polar radius to angstrom.
How to Convert Angstrom to Earth's Polar Radius
1 A = 1.57313035463093e-17 R_p
Example: convert 15 A to R_p:
15 A = 15 × 1.57313035463093e-17 R_p = 2.3596955319464e-16 R_p
Angstrom to Earth's Polar Radius Conversion Table
| angstrom | Earth's polar 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 Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
