Convert astronomical unit to X-unit
Please provide values below to convert astronomical unit [AU, UA] to X-unit [X], or Convert X-unit to astronomical unit.
1 AU, UA = 1.4929e+24 X. To convert astronomical unit to X-unit, multiply the value by 1.4929e+24; to go the other way, divide by it (1 X = 6.6985e-25 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 AU, UA = 1.4929e+24 X
- 1 X = 6.6985e-25 AU, UA
- 10 AU, UA = 1.4929e+25 X
- 100 AU, UA = 1.4929e+26 X
How to Convert Astronomical Unit to X-Unit
1 AU, UA = 1.49287353005748e+24 X
Example: convert 15 AU, UA to X:
15 AU, UA = 15 × 1.49287353005748e+24 X = 2.23931029508622e+25 X

Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
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.
