Convert X-unit to Earth's equatorial radius
Enter a value below to convert X-unit [X] to Earth's equatorial radius [R_e]. Reverse conversion: 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.

X-Unit: Definition and Use
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: Definition and Use
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.
