Chain (ch). A chain is 66 feet (20.1168 m), a surveying unit; 80 chains make one mile.
Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
There are 2.12635 × 10⁻¹⁵ light years in one chain.
Multiply the number of chains by 2.12635 × 10⁻¹⁵. For example, 10 chains equal 2.12635 × 10⁻¹⁴ light years.
One light year equals 470,290,029,854,689 chains.
2.12635 × 10⁻¹² light years. Other common values: 100 chains = 2.12635 × 10⁻¹³ light years and 10,000 chains = 2.12635 × 10⁻¹¹ light years.
