How many years are there in 1 second?

Ther are .31536 years in 1 second.

According to that answer 4 seconds = 0.31536*4 = 1.26144 years so 4 seconds is longer than 1 year! I think not.

If you take an average year as 365.25 days (to allow for leap years), then, 1 second is 0.00000003169 years, or 3.169*10-8 years.
