How to convert Ri to Light-second

Conversion factor and calculation steps from Ri (ri) 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 ri = 3927.27272727 m

1 ls = 299792458 m

1 ri × 3927.27272727 = 3927.27272727 m

3927.27272727 m ÷ 299792458 = 1.30999717e-5 ls
