That is the distance that light travels in 3.2 years, this is equal to
3.2 x 299792458m/s x (60 x 60 x 24 x 365)s = 3.0254 x 10^16 m

3.2 light years is roughly one parsec.
What's a parsec? That's how far away something needs to be in order to give a parallax of one second of arc when your baseline is one astronomical unit. That's a reasonable baseline if you are looking at nearby stars from Earth, and wait a few months and look again. If the observing location is shifted by 93,000,000 miles, then a star 3.26 light years away (none are quite that close, but almost) will shift by 1 arcsec against the field of background stars. What's an arcsec? 1/60 of a degree is an arcmin, and 1/60 of an arcmin is an arcsec. It takes a telescope with a 4-inch lens to resolve that tiny amount of shift. A little trig here, as an exercise for the reader, 1 radian is 180/pi = 57.296 degrees; multiply by 3600 to see 1 rad = 206,265 arcsec. Multiply by 92 955 887.6 miles (accepted standard value) and find 1 parsec = 1.917 x 10^19 miles, approx what previous answers say. .

3.2 Light years = [3.2 * (3*10^8m/sec^2)] M
The distance travelled by Light in a period of 3 years and 2 months

light travels at 184,000 miles a second so 3.2 light years is the distance it would travel in 3.2 years.

This question doesn't really make sense, but if you're looking for a unit that represents 3.2 ly, then you're probably looking for the parsec, which is 3.26 ly.

distance=speed*time
in this case time =3.2 light years=3.2*365.2422 days*24 hours*3600seconds=
so distance in meters=100982163.456*100982163.456
=3027369099663.2014.848
in kilometers
=3027369099663.2014848
in miles
=Result: 3027369099 km = 1168873743.84 miles

The answer in distance is 18,770,227,200,000 miles. This is based on the the speed of light being 186,000 miles per second.

The distance that light travels in a vacuum in one year, approximately 9.46 trillion (9.46 Ã 1012) kilometers or 5.88 trillion (5.88 Ã 1012) miles.
3.2 light years = 18,880,000,000,000 miles
