Answer
Around 9.461 trillion kilometers make up one light-year.
Work Step by Step
To convert light-years to kilometers, we need to know the speed of light and the number of seconds in one year. The speed of light in a vacuum is approximately 299,792,458 meters per second, and one year has approximately 31,557,600 seconds (365.25 days x 24 hours x 60 minutes x 60 seconds). Therefore, we can calculate the distance of one light-year in kilometers as follows:
Distance = Speed x Time
Distance = (299,792,458 m/s) x (31,557,600 s/year)
Distance = 9.461 trillion kilometers
