One light year equals the distance that light travels in a vacuum in one year. Give this distance in kilometers, assuming that the speed of propagation of light in a vacuum is 300,000 km / s
In order to convert a light year to kilometers, you must first calculate the number of seconds in one calendar year:
1 year = 365 days = 365 * 24 = 8760 hours = 8760 * 60 = 525600 minutes * 60 = 31536000 seconds.
31536000 * 300000 = 9460800000000 kilometers or 9460.8 billion kilometers.
Answer: 1 light year is equal to 9,460.8 billion kilometers.
