given that an AU is 1.5x10^8kilometer and a light year is about 10^13 kilometers, how many AU are in a light year ?

63240 Au are in a lght year.

9467280000000 / 149598500 since the top is 1 light year the distance light travels in a year and 1 AU is the bottom

then we just solve and get a number that is roughly 63241

here is a site to help you out http://www.convertunits.com/from/AU/to/light+year
