I think you are commenting on the widespread, confusing use of "mHz" which literally means milli-Hz. How this "unit" came to substitute for MHz is a mystery to me. As an engineer, I tried to use what I was taught--lower-case multipliers are <1 and upper-case multipliers are >1. "K" and "k" appear to have gone the same route as "M" and "m". I don't know why or when these changed--probably when I was not looking.
