How to convert Nanometer to Light-second

Conversion factor and calculation steps from Nanometer (nm) 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 nm = 1.00000000e-9 m

1 ls = 299792458 m

1 nm × 1.00000000e-9 = 1.00000000e-9 m

1.00000000e-9 m ÷ 299792458 = 3.33564095e-18 ls
