Convert chain (US survey) to astronomical unit
Please provide values below to convert chain (US survey) [ch (US)] to astronomical unit [AU, UA], or Convert astronomical unit to chain (US survey).
1 ch (US) = 1.3447e-10 AU, UA. To convert chain (US survey) to astronomical unit, multiply the value by 1.3447e-10; to go the other way, divide by it (1 AU, UA = 7436449708.91 ch (US)). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 ch (US) = 1.3447e-10 AU, UA
- 1 AU, UA = 7436449708.91 ch (US)
- 10 ch (US) = 1.34472771167e-09 AU, UA

Chain (Us Survey)
A U.S. survey chain is a unit of length equal to 66 U.S. survey feet.
History/Origin
The U.S. survey chain is based on the U.S. survey foot, which was slightly different from the international foot. The use of survey units was officially phased out in 2022.
Current Use
The U.S. survey chain was used for land surveying in the United States.
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.
Frequently Asked Questions
What is 1 chain (US survey) in astronomical unit?
