How to convert Fathom to Light-second

Conversion factor and calculation steps from Fathom (ftm) 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 ftm = 1.8288 m

1 ls = 299792458 m

1 ftm × 1.8288 = 1.8288 m

1.8288 m ÷ 299792458 = 6.10022017e-9 ls
