The one thing you want to keep in mind though is that Hertz does not actually mean inverse seconds, it means cycles per second. So, if you're talking about a car going so many meters per second, you can't say it's going meter Hertz, you have to say meters per second.

写成5每秒，或5赫兹,你们要记住的是赫兹,并不等于秒的倒数，它是每秒的循环数，如果你们说,一辆车一秒可以走多少米,你不能说它走了米赫兹。
