120 kHz is equal to 120,000 Hz.
Since 1 kilohertz (kHz) equals 1,000 hertz (Hz), converting 120 kHz to Hz involves multiplying 120 by 1,000. This results in 120,000 Hz, which is the frequency measurement in hertz. The conversion makes it easy to compare and analyze audio, radio, and signal frequencies more precisely.
Understanding the Conversion Process
The process of converting kHz to Hz is straightforward because the prefix ‘kilo’ signifies a multiplication by 1,000. To get Hz from kHz, you simply multiply the number of kilohertz by 1,000. For example, 120 kHz times 1,000 gives 120,000 Hz. This conversion helps in fields like electronics, communication, and physics where exact frequency measurement matters.

Conversion Formula
The formula to convert kilohertz (kHz) to hertz (Hz) is simple: Hz = kHz × 1,000. This works because the ‘kilo’ prefix in SI units stands for 1,000. For example, converting 50 kHz involves multiplying 50 by 1,000, resulting in 50,000 Hz. The multiplication shifts the decimal three places to the right, increasing the value by 1,000 times.
Conversion Example
- Convert 200 kHz to Hz:
- Multiply 200 by 1,000.
- 200 × 1,000 = 200,000 Hz.
- Result is 200,000 Hz.
- Convert 75 kHz to Hz:
- 75 × 1,000 = 75,000 Hz.
- Result is 75,000 Hz.
- Convert 5.5 kHz to Hz:
- 5.5 × 1,000 = 5,500 Hz.
- Result is 5,500 Hz.
- Convert 0.5 kHz to Hz:
- 0.5 × 1,000 = 500 Hz.
- Result is 500 Hz.

Conversion Definitions
kHz
The kilohertz (kHz) is a unit of frequency equal to 1,000 cycles per second. It is used to measure radio, audio, and electromagnetic wave frequencies, making it practical for describing signals in telecommunications and broadcasting equipment.
Hz
Hertz (Hz) represents cycles per second, and it measures the frequency of periodic events such as sound waves and electromagnetic signals. It is the base SI unit for frequency, defining how many oscillations occur in one second.
Conversion FAQs
Why do we multiply kilohertz by 1,000 to get hertz?
Because the prefix ‘kilo’ in SI units signifies 1,000 times. So, to convert 120 kHz into Hz, we multiply 120 by 1,000, which shifts the decimal point three places to the right, giving 120,000 Hz.
Can I convert kHz to Hz without a calculator?
Yes, since the conversion involves multiplying by 1,000, you can do it manually by adding three zeros to the number of kilohertz. For example, 50 kHz becomes 50,000 Hz just by appending zeros.
What other units can I convert kHz to?
Besides Hz, kilohertz can be converted to megahertz (MHz) or gigahertz (GHz), but these conversions involve dividing by 1,000 or 1,000,000 respectively. For example, 120 kHz is 0.12 MHz.
Is there a practical reason to convert kHz to Hz?
Yes, many scientific calculations and electronic measurements require precise frequency values in Hz, especially when dealing with high-frequency signals or digital systems where exactness is critical.
