I continued doubling the seconds untill i got to week 36..The week 36 shows me 3.435974e+10..I don't know if it was an error? Sorry, please more help.

It must be an error. Probably your calculator can't handle this many digits.

You can type your numbers into the Google search box. It can handle numbers with any number of digits.

You're welcome.

Since there are 60 seconds in a minute, and 60 minutes in an hour, divide your number of seconds by 360 to find the number of hours.
