How many microseconds is one CPU cycle?

I had to figure this out (again), so I am writing this down for future reference.

(1*10^6 microseconds/1second)(1second/CpuHz)1 cycle = ? microseconds

For example, if my CPU is 18.432MHz, then the formula would be:

(1000000/18432000) = microseconds of 1 CPU cycle, which is 0.054 uS
