Problem is: 58,000.000 KM being converted to light-years

I did 58,000,000 x 365 x 24 x 60 x 60 and came up with 0.0000006131 and converted that to 6 x 10 to the negative 6. My teacher says it should have been 6 x 10 to the negative 5? Could you explain where I went wrong? Thank you so much for any help you can give me.

Your answer is actually correct. It should be raised to -6, not -5. For the solution:
1 Light Year = 9.46 x 10^12 km
Thus,
58,000,000 km * (1 light year / 9.46 x 10^12 km)
= 6.131 x 10^-6 light year
Thank you Jai - I wish I had the nerve to tell her she was wrong, I tried that once and oh boy, let's just say things did not work out after that. I'll just know I was right and accept the 2 points off. Thank You again Kyle
