Convert Earth's equatorial radius to X-unit
Please provide values below to convert Earth's equatorial radius [R_e] to X-unit [X], or Convert X-unit to Earth's equatorial radius.
1 R_e = 6.3649e+19 X. To convert Earth's equatorial radius to X-unit, multiply the value by 6.3649e+19; to go the other way, divide by it (1 X = 1.5711e-20 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 R_e = 6.3649e+19 X
- 1 X = 1.5711e-20 R_e
- 10 R_e = 6.3649e+20 X
- 100 R_e = 6.3649e+21 X
How to Convert Earth's Equatorial Radius to X-Unit

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.
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.
