How many years are there in 1 second?

Answer 1

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.

Answer 2

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.

a ) 3.1×10-8

b) 3.1×8

c)3.1×10 -16
