Convert X-unit to Earth's polar radius
Please provide values below to convert X-unit [X] to Earth's polar radius [R_p], or Convert Earth's polar radius to X-unit.
1 X = 1.5764e-20 R_p. To convert X-unit to Earth's polar radius, multiply the value by 1.5764e-20; to go the other way, divide by it (1 R_p = 6.3436e+19 X). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 X = 1.5764e-20 R_p
- 1 R_p = 6.3436e+19 X
- 10 X = 1.5764e-19 R_p
- 100 X = 1.5764e-18 R_p
How to Convert X-Unit to Earth's Polar Radius
1 X = 1.57640246576857e-20 R_p
Example: convert 15 X to R_p:
15 X = 15 × 1.57640246576857e-20 R_p = 2.36460369865285e-19 R_p

X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
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.
