The conversion of 20,000 Hz to kHz results in 20 kHz.
Since 1 kilohertz (kHz) equals 1,000 hertz (Hz), dividing 20,000 Hz by 1,000 gives the value in kHz. Therefore, 20,000 Hz equals 20 kHz, which is a common frequency used in audio and signal processing applications, representing a high-pitched sound or signal frequency.

Conversion Formula
The formula for converting Hz to kHz is simple: divide the number of hertz by 1,000, because 1 kHz equals 1,000 Hz. This works because the prefix ‘kilo-‘ in the metric system indicates thousand. For example, if you have 5,000 Hz, dividing by 1,000 gives 5 kHz. So, the math is: kHz = Hz / 1000.
Conversion Example
- Example 1: Convert 15,000 Hz to kHz.
- Divide 15,000 by 1,000.
- 15,000 / 1000 = 15 kHz.
- Answer: 15 kHz.
- Example 2: Convert 8,500 Hz to kHz.
- Divide 8,500 by 1,000.
- 8,500 / 1000 = 8.5 kHz.
- Answer: 8.5 kHz.
- Example 3: Convert 22,750 Hz to kHz.
- Divide 22,750 by 1,000.
- 22,750 / 1000 = 22.75 kHz.
- Answer: 22.75 kHz.
- Example 4: Convert 1,200 Hz to kHz.
- Divide 1,200 by 1,000.
- 1,200 / 1000 = 1.2 kHz.
- Answer: 1.2 kHz.

Conversion Definitions
Hz
Hertz (Hz) is the basic unit of frequency measuring how many cycles or oscillations occur per second in a wave or signal. It is used in physics, engineering, and audio to quantify how often events happen within a second, making it crucial for understanding sound and electromagnetic waves.
kHz
Kilohertz (kHz) is a unit of frequency equal to 1,000 Hertz. It is commonly used to measure higher frequencies such as audio pitches, radio signals, and other electromagnetic waves, allowing easier expression of large frequency values in a manageable scale.
Conversion FAQs
What does 20,000 Hz equal in kilohertz?
20,000 Hz equals 20 kHz because dividing 20,000 by 1,000 gives the value in kilohertz, simplifying the large number into a more manageable figure used in audio and radio frequency contexts.
Why is dividing Hz by 1000 the correct way to convert to kHz?
This is because the prefix ‘kilo-‘ indicates a thousand units. Therefore, to convert Hz to kHz, dividing by 1,000 directly scales down the frequency to the kilohertz range, which is more practical for high-frequency measurements.
Can the conversion from Hz to kHz be used for frequencies above 1 MHz?
Yes, but for frequencies above 1 MHz, it is often more convenient to use MHz (megahertz), where 1 MHz equals 1,000,000 Hz. Converting to kHz can still be done by dividing by 1,000, but MHz might be more suitable for very high frequencies.
What are some common applications of 20 kHz frequencies?
20 kHz frequencies are used in audio testing, ultrasonic imaging, and some radio communications. They represent the upper limit of human hearing and are important in designing audio equipment and ultrasonic devices.
