How to convert Chain to Light-second

Conversion factor and calculation steps from Chain (ch) to Light-second (ls).

Conversion logic

Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.

1 ch = 20.1168 m

1 ls = 299792458 m

1 ch × 20.1168 = 20.1168 m

20.1168 m ÷ 299792458 = 6.71024219e-8 ls
