Convert angstrom to Earth's polar radius
Enter a value below to convert angstrom [A] to Earth's polar radius [R_p]. Reverse conversion: Convert Earth's polar radius to angstrom.
1 A = 1.5731e-17 R_p. To convert angstrom to Earth's polar radius, multiply the value by 1.5731e-17; to go the other way, divide by it (1 R_p = 6.3568e+16 A). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Angstrom: Definition and Use
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: Definition and Use
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.
Angstrom to Earth's Polar Radius: Frequently Asked Questions
What is 1 angstrom in Earth's polar radius?
1 angstrom (A) = 1.5731e-17 Earth's polar radius (R_p).
How do you convert angstrom to Earth's polar radius?
Multiply the angstrom value by 1.5731e-17. For example, 25 A × 1.5731e-17 = 3.9328e-16 R_p.
