How to Convert Chain (Us Survey) to Earth's Distance From Sun
1 ch (US) = 1.34472771166923e-10 AU_dist
Example: convert 15 ch (US) to AU_dist:
15 ch (US) = 15 × 1.34472771166923e-10 AU_dist = 2.01709156750384e-09 AU_dist

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.
Earth's Distance From Sun
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
