Since each day has 24 hours (except for days affected by changing into and out of daylight savings time), simply multiply 687 by 24. The answer is 16,488 hours.

687 days x 24 hrs/day = 16,488 hours, but if you catch a leap year (with 29 days February, like 2004 or 2008), you have to add extra 24 hours, and the answer will be 16,512 hours.
