The distance travelled by light in 1 year. Taking an year as 365.25 days, we can work it out:
Light moves at a velocity of about 300,000 kilometers (km) each second.
There are 31557600 seconds in a year.
9467280000000 kuilometers is the value.

a light year is a measure of distance , specifically the distance traveled by light over the course of one year . . .
speed of light = 2.98 x 10^8 m/s
so . . .
2.98x10^8 meters/sec x 3600 sec/hour x 24 hours/day x 365.25 days/year = 9.40x10^15 meters or
9.40x10^12 kilometers
(note: you cannot accurately get this information to more deicimal places because there are not enough significant digits in your calculations . . . so 940461.... is not a valid measurement )
