Example:

Two close stellar neighbors of Earth are Rigel Centaurus (4.3 light–years away) and Sirius (8.7 light–years away). Use c, the speed of light (9.5 1015 meters per year) to convert the distances from the Earth to these stars into meters:

To Rigel Centaurus: 4.3 yr (9.5 1015 m/yr).

To Sirius: 8.7 yr (9.5 1015 m/yr).
