Convert centimeter to astronomical unit
Please provide values below to convert centimeter [cm] to astronomical unit [AU, UA], or Convert astronomical unit to centimeter.
1 cm = 6.6846e-14 AU, UA. To convert centimeter to astronomical unit, multiply the value by 6.6846e-14; to go the other way, divide by it (1 AU, UA = 1.4960e+13 cm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cm = 6.6846e-14 AU, UA
- 1 AU, UA = 1.4960e+13 cm
- 10 cm = 6.6846e-13 AU, UA

Centimeter
A centimeter is a unit of length in the metric system, equal to one-hundredth of a meter.
History/Origin
The prefix "centi-" comes from the Latin word "centum," meaning hundred. The centimeter was part of the original metric system established in France in 1795.
Current Use
The centimeter is a very common unit of measurement for everyday objects and is used in many fields, including science, engineering, and fashion.
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.
