About converting Hertz to Kilohertz
Hertz (Hz) and Kilohertz (kHz) are both units of frequency, so converting between them is a single multiplication: multiply your Hertz figure by 0.001. Ten Hertz comes to 0.01 Kilohertz, and a hundred works out at 0.1 Kilohertz.
Rule of thumb: going from Hertz to Kilohertz divides, so the figure always shrinks — it takes about 1,000 Hertz to make a single Kilohertz. If your answer came out bigger, you have the conversion the wrong way round.
What is a Hertz?
The hertz is one cycle per second — nothing more. It is named after Heinrich Hertz, who demonstrated experimentally that electromagnetic waves exist, confirming what until then had been theory. The unit itself is younger than it looks: engineers said "cycles per second", abbreviated cps, until hertz was formally adopted in 1960. Its reach is remarkable for so plain a definition. Mains electricity alternates at 50 or 60 Hz, human hearing starts at roughly 20 Hz, and a monitor advertised at 144 Hz is simply redrawing itself 144 times a second. Anything that repeats can be counted in hertz.
What is a Kilohertz?
The kilohertz is the range of sound and of the oldest broadcast radio. The top of human hearing sits somewhere near 20 kHz in a young ear, and digital audio is sampled in kilohertz — CD audio at 44.1 kHz, most video and studio work at 48 kHz or above — because a sample rate has to comfortably exceed the highest frequency you want to capture. AM radio is the other kilohertz territory: the numbers on an AM dial are station frequencies in kilohertz, which is why they run to three or four digits while the FM dial beside them shows tidy two-digit megahertz.
To put both in perspective: a screen refreshing 60 times a second runs at 60 hertz, while AM radio stations sit around 1,000 kilohertz on the dial.

Frequently asked questions
How many Kilohertz are in one Hertz?
There are 0.001 Kilohertz in one Hertz.
How do I convert Hertz to Kilohertz?
Multiply the number of Hertz by 0.001. For example, 10 Hertz = 0.01 Kilohertz.
What is 100 Hertz in Kilohertz?
100 Hertz is equal to 0.1 Kilohertz.
How do I convert Kilohertz to Hertz?
Multiply the Kilohertz value by 1,000 (or divide by 0.001).
Is this Hertz to Kilohertz conversion exact?
Yes, exactly. Both units are fixed against the same base by definition, and 1 Hertz = 0.001 Kilohertz is the complete value — nothing is rounded away.
