What is one light year in seconds need it to written out in the conversion format

I'm going to do this in meters which will turn into km. which you can then convert into miles.

The speed of light is 2.998 * 10 ^8 meters /second

2.998*10^8m/s[3600 s/hr]*[24 hrs/day]*[365 days/year]

2.998*10^8 * 3600 * 24 * 365 = 9.45*10^15 m/year

9.45*10^15 m/year / 1000 m/km = 9.45 * 10^12 km/year

If you want miles, just divide this number by 1.6

9.45 * 10^12 / 1.6 = 5.91 * 10^12 miles / year. When you google this, the answer they give is 5.87 * 10^12 miles / yr. The difference is in where you round, the use of an approximate 1.6 and the length of a year.
