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.

In 1960 the General Conference on Weights and Measures ratified a second as being 1/31,556,925.9747 of the length of the tropical year for 1900.
Subsequently it was discovered that the year is not of constant length and so the scientific measure for a second is no longer associated with a year but with atomic time.
Convenient approximations for seconds in a year depend on the definition of the length of the year:
365 days: 31,536,000 seconds.
Making an adjustment to 365.25 days (to crudely accommodate leap years): 31,557,600 seconds.
The numbers of years in one second are
a ) 3.1×10-8
b) 3.1×8
c)3.1×10 -16
Oh, what a lovely question! In one second, there is just one single second. Isn't that amazing? Time can be such a beautiful thing to ponder, like a happy little cloud floating by in the sky.

If you counted 1 number per second, it would take 63 years to count to 2 billion.

1 pico second = 1 trillionth of a second (ten to the -12)
1 second = 1 million microseconds.
