If a star is shown to be 33.11 trillion kilometers away, how many light years would that be?

After reading your question, I went and looked on line for a definition of 'light year',

since its getting late and I didn't feel like calculating it.

The definition I found is: 1 light year = 9.4605284 x 10¹⁵ meters

OK. 1 trillion = 1 x 10¹².

Also, 1 kilometer = 1,000 meters,

so 1 trillion kilometers = 1 x 10¹⁵ meters.

And we're ready now to find the number you want.

33.11 x 10¹⁵ meters / 9.4605284 x 10¹⁵ meters = 3.5 light years
