Convert chain to astronomical unit
Please provide values below to convert chain [ch] to astronomical unit [AU, UA], or Convert astronomical unit to chain.
1 ch = 1.3447e-10 AU, UA. To convert chain to astronomical unit, multiply the value by 1.3447e-10; to go the other way, divide by it (1 AU, UA = 7436464581.84 ch). 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 = 1.3447e-10 AU, UA
- 1 AU, UA = 7436464581.84 ch
- 10 ch = 1.34472502221e-09 AU, UA
- 100 ch = 1.34472502221e-08 AU, UA
How to Convert Chain to Astronomical Unit
1 ch = 1.3447250222125e-10 AU, UA
Example: convert 15 ch to AU, UA:
15 ch = 15 × 1.3447250222125e-10 AU, UA = 2.01708753331875e-09 AU, UA

Chain
A chain is a unit of length equal to 66 feet, or 22 yards.
History/Origin
The chain was developed by English surveyor Edmund Gunter in the early 17th century. It was designed to be a convenient length for surveying land.
Current Use
The chain is still used in some surveying applications and is the length of a cricket pitch.
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 in astronomical unit?
1 chain (ch) = 1.3447e-10 astronomical unit (AU, UA).
How do you convert chain to astronomical unit?
Multiply the chain value by 1.3447e-10. For example, 25 ch × 1.3447e-10 = 3.36181255553e-09 AU, UA.
What is 10 chain in astronomical unit?
10 ch = 1.34472502221e-09 AU, UA.
Which unit is larger, the chain or the astronomical unit?
The astronomical unit is the larger unit: 1 ch equals only 1.3447e-10 AU, UA.
