Formula in converting year to second?

Answer 1

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

1 year = 365 days = (365 x 24 x 60 x 60) = 31,536,000 seconds.

If you want to convert a number of years to seconds:

-- Take the number of years.

-- Multiply by 31,536,000.

-- The answer is the number of seconds.
