A cetifortnight i.e one hundredth of a fortnight should be 3.36 hours right? I know that should be 12,096 seconds since 3,600 seconds = 1 hour Then how come several sites have stated this "12,096 seconds = 1 centifortnight. 2.4 hours" is there something I am getting wrong?

You are right, and you've had confirmation from two other sites: http://www.mathhelpforum.com/mathhe...ts184573.html http://sosmath.com/CBB/viewtopic.php?t=54996 The "2.4 hours" is one person's mistake. The reason it appears on more than one website is that some websites "aggregate" content (i.e. copy and paste).

A fortnight is 14 days = 336 hours, thus 1/100 fortnight is 3.36 hours.

Google is a good way to check yourself on these sorts of things: http://www.google.com/search?q=1+fortnight+%2F+100
