1 Billion Seconds Equals to

We know that 1 year = 365.25 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

=> 1 Year = 365.25 x 24 x 60 x 60 Seconds

But 1 billion seconds = ?

1 Year = 365.25 x 24 x 60 x 60 Seconds

    ?     =  1000000000 Seconds

$? = \frac{1000000000}{365.25 x 24 x 60 x 60} \mathrm{years}$ = 31. 68 years.
