A light year is 9,460,730,472,580.8 km. Multiply that by 1000 to get meters in a light year, then multiply that by 4.2 to get the number of meters (its a really big number).

4.2 x 365.25 x 24 x 60 x 60 x 3 x 10^10 meters
years x number of days x number of hours in a day x number of minutes in an hour x number of seconds in a minute x velocity of light in vacuum in meters
Simply multiply the above numbers and raise the exponent suiably.

1 light year is equal to the distance light travels in one year in a vacuum, or 9,460,730,472,580.8 kilometers.
That's 9,460,730,472,580,800 meters per year.
4.2 light years would be 37,842,921,890,323,200 meters.
