4 light years means distance traveled by light in 4 years of time.
Lets see how many seconds does 4 year have
4*365*24*60*60
126144000 sec
Now multiply this with velocity of light
3*10^8*126144000
378432000*10^8
3.78432*10^16 m.....
The standard SI unit for measuring distance is the meter. One light year is approximately 9.461 x 10^15 meters, so 4 light years would be 3.7844 x 10^16 meters.
