How to convert Light-year to Light-second

Conversion factor and calculation steps from Light-year (ly) 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 ly = 9.46073047e15 m

1 ls = 299792458 m

1 ly × 9.46073047e15 = 9.46073047e15 m

9.46073047e15 m ÷ 299792458 = 31557600 ls
