How to convert light-years into astronomical units?

To convert light-years into astronomical units, preform the following calculations:

1 ly = 63,241.08 AU

distance in light-years × 63,241.08 = distance in astronomical units

Example:

15 ly

15 light-years × 63,241.08 = 948,616.2 astronomical units
