Is My Clock Cycle Calculation Accurate for a 2.5 GHz CPU?

[DanjoJojo]

TL;DR

What is the duration of a clock cycle (in nanoseconds) for a CPU running at 2.5 GHz?

So far I have come to the understanding that a nanosecond is one billionth of a second or 10-9 seconds. So I found this formula to calculate the clock cycle in nanoseconds, for a CPU running at 2.5 GHz.

10^-9 x 2.5 x 10^9 = 2.5 nanoseconds

Am I missing any important steps with my calculation? Is this accurate?

A 1GHz frequency would be 1ns period. A higher frequency would involve a smaller period. What formula are you using?

Also, is this for schoolwork?

Period is inversely proportional to frequency. I don't see the 'devide' operation in your calculation.
