A kilohertz is a unit for measuring how fast something repeats: how many times it happens each second. That kind of counting is called frequency. One kilohertz is 1,000 hertz, which means 1,000 times a second.

A kilohertz kilohertz是 a unit一個單位 for measuring how fast something repeats用來量某件事重複得多快：how many times it happens each second也就是它每一秒發生幾次。 That kind of counting這種計算方式 is called被稱為 frequency頻率。 One kilohertz一個kilohertz是 1,000 hertz一千個hertz，which means也就是 1,000 times a second一秒一千次。

People use it a lot for sound and for radio signals. A deep hum might be measured in hertz; many AM radio stations are still given in kilohertz. The short form is kHz.

People人們 use it a lot經常用它 for sound and for radio signals用在聲音和無線電訊號上。 A deep hum一個低沉的嗡嗡聲 might be measured in hertz可能會用hertz來量；many AM radio stations很多AM廣播電台 are still given in kilohertz仍然是用kilohertz標示的。 The short form簡寫 is是 kHz kHz。

Unlike a kilobyte, this kilo- is the ordinary science kilo-: it is exactly 1,000, not 1,024. Hertz is named after a scientist. After a number, technical English usually keeps the same form: “800 kilohertz,” not “800 kilohertzes.” Though actually, FM radio is usually talked about in megahertz, a much bigger step; if you put an FM station in kilohertz, the number will look strangely huge.

Unlike a kilobyte跟kilobyte不一樣，this kilo-這裡的kilo-是 the ordinary science kilo-一般科學上的kilo-：it is exactly就正好是 1,000一千，not 1,024而不是1,024。 Hertz Hertz這個字 is named after一個科學家的名字 a scientist是以...命名的。 After a number在數字後面，technical English技術英語 usually keeps the same form通常保持同樣的形式：“800 kilohertz,”「800 kilohertz」，not “800 kilohertzes.”而不是「800 kilohertzes」。 Though actually不過其實 FM radio FM廣播 is usually talked about in megahertz通常是用megahertz來講的，a much bigger step一個大得多的單位；if you put an FM station in kilohertz如果你把FM電台的頻率換成kilohertz，the number will look strangely huge數字看起來會大得很奇怪。
