By mathematical computation, at 60 seconds per minute, 60
minutes per hour, 24 hours per day, and 365.25 days per year, the
answer would be : 31,557,600 seconds per year, 3,155,760,000 per
century, and **9,467,280,000** in three centuries. However, by
the more precise definition (which requires adjustment of the
calendar with "leap seconds" and omitted "leap days"), there are
31556925.9747 seconds in a standard SI year, which equals
3,155,692,597 (and a fraction) per century and **9,467,077,792**
(and a fraction) in three centuries.
