Convert chain (US survey) to light year
Please provide values below to convert chain (US survey) [ch (US)] to light year [ly], or Convert light year to chain (US survey).
1 ch (US) = 2.1264e-15 ly. To convert chain (US survey) to light year, multiply the value by 2.1264e-15; to go the other way, divide by it (1 ly = 4.7029e+14 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) = 2.1264e-15 ly
- 1 ly = 4.7029e+14 ch (US)
- 10 ch (US) = 2.1264e-14 ly
- 100 ch (US) = 2.1264e-13 ly
How to Convert Chain (Us Survey) to Light Year

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.
Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
