Answer
One fortnight has 1209600000000 microseconds
Work Step by Step
Since a fortnight is equal to 2 weeks, we need to find the number of seconds in 2 weeks. Therefore,
Number of seconds in 2 weeks = 2( number of seconds in 1 week)
Number of seconds in 2 weeks = 2(7*24*60*60) seconds
Number of seconds in 2 weeks = 1209600
It is known that one second = 1000000 microseconds.
Hence, the number of microseconds in 2 weeks = 1209600*1000000 = 1209600000000
