How to convert Light-second to Light-year

Conversion factor and calculation steps from Light-second (ls) to Light-year (ly).

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 ls = 299792458 m

1 ly = 9.46073047e15 m

1 ls × 299792458 = 299792458 m

299792458 m ÷ 9.46073047e15 = 3.16880878e-8 ly
