Convert X-unit to Earth's equatorial radius
Please provide values below to convert X-unit [X] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to X-unit.
1 X = 1.5711e-20 R_e. To convert X-unit to Earth's equatorial radius, multiply the value by 1.5711e-20; to go the other way, divide by it (1 R_e = 6.3649e+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 = 1.5711e-20 R_e
- 1 R_e = 6.3649e+19 X
- 10 X = 1.5711e-19 R_e
- 100 X = 1.5711e-18 R_e
How to Convert X-Unit to Earth's Equatorial Radius
1 X = 1.5711170832486e-20 R_e
Example: convert 15 X to R_e:
15 X = 15 × 1.5711170832486e-20 R_e = 2.35667562487291e-19 R_e

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 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.
