Nobody answered right because noboby understood the question right. When we look on the night sky with a telescope we see into the past. If the light takes 1 light year to arrive from point A to Earth, how many earth years have passed since the light begun to travell from point A to Earth?
A light year is a measure of distance. A year is a measure of time. Asking what a light year is in years is like asking what a metre is in seconds.
A light year is a unit of DISTANCE, not a unit of time. 1 light year = the distance light travels in one year is close to 6 trillion MILES (not 6 trillion years).
A light year is the distance light travels in one year.
Light travels at a velocity of approximately 300,000 kilometers/sec.
There are 60*60*24*365=31,536,000.00 seconds/yr.
So, a light year is approximately 300,000*31,536,000=9,460,528,400,000 kilometers.
The distance to the nearest star (outside of our solar system) is about 4.24 light years.

Light years is a distance.
Earth years is a time
you can't equate them =S
Earth years is a time

1 year
Exactly 1,386 years
One julian year

I agree with Nasa.
Earth Years measure time. Light years measure distance. They cannot be compared like that since they measure two completely different things.
A light year is the distance light travels in an earth year. So the answer to your question is 1.
A light year is 5,878,630,000,000 miles (about 6 trillion miles) just figure out how fast you are going to travel and you can figure out how long it will take you... I would recommend finding a warm hole to speed things up a bit!
1 light year is how many times 60 battery operated monkeys can go round the earth's
circumference in 1 year; from this distance is calculated as a relative parameter.
An earth year is a totally different unit of measurement, as correctly pointed out previously.

1 light year equals 10 trillion kilometersand 1 light year isn't years its distance not days or years on earth so when they say it takes 10 light years to get there they mean it takes 100 trillion kilometers thanks for asking
1 lightyear = the distance light travels in one year is close to 6 trillion miles, not years in earth
Too technical for me; but here's a place that might help:

A light year is equal to 6 trillion years.
A light year is the earth having light day and night for a whole years...DUH!!!
A light year is not measured in time it is measured in distance. One light year equals 5.9 quadrillion miles.
Light year is used for measuring distance but Earth year is unit of time. Relating them will be like adding monkeys to donkeys.
