To convert from kilohertz (kHz) to gigahertz (GHz), use the following formula:
Let's convert 5 kilohertz (kHz) to gigahertz (GHz).
Using the formula:
Therefore, 5 kilohertz (kHz) is equal to gigahertz (GHz).
Here are some quick reference conversions from kilohertz (kHz) to gigahertz (GHz):

A kilohertz (kHz) is a unit of frequency in the International System of Units (SI), equal to one thousand hertz (1000 Hz). The plural form is kilohertz.
It's a term you'll encounter in everything from sound and radio to the history of computing.
Your ability to perceive sound, from the deepest bass to the highest treble, is measured in hertz and kilohertz.
The range of human hearing typically falls between 20 Hz and 20 kilohertz (20,000 Hz).
The frequencies most sensitive to the human ear, particularly for understanding speech, are concentrated in the range of 1 to 4 kHz. This is why audio engineers and audiologists pay close attention to this specific spectrum when mixing music or conducting hearing tests.
Kilohertz is the fundamental unit used for AM (Amplitude Modulation) radio broadcasting.
AM radio stations operate in a frequency range from 535 to 1705 kilohertz in the Americas, often referred to as the medium wave band.
Each station is assigned a specific frequency, like 820 kHz or 1010 kHz, which your radio receiver tunes into to capture the broadcast signal. This contrasts with FM radio, which broadcasts in the much higher megahertz (MHz) range.
While today's computers boast processor speeds in gigahertz (GHz), the pioneers of computing operated at much slower speeds measured in kilohertz.
For instance, the Intel 4004, the world's first commercial microprocessor, was released in 1971 with a clock speed of just 740 kHz.
Beyond computing, kilohertz frequencies are also crucial in other technologies. A key example is medical ultrasound, where transducers emit sound waves in the high kHz to low MHz range to create diagnostic images of the body's organs and tissues.
A gigahertz (GHz) is a unit of frequency in the International System of Units (SI), equal to one billion hertz (109 Hz). The plural form is gigahertz.
The gigahertz measurement is famously used to indicate a computer's CPU clock speed, which tells you how many processing cycles it can complete per second.
For example, a 3.2 GHz processor can handle 3.2 billion cycles every second.
While a higher GHz number often suggests a faster processor, overall performance also depends on other critical factors, such as the number of cores and the chip's architecture.
Your daily wireless connections, like Wi-Fi and Bluetooth, operate on specific gigahertz frequency bands.
The most common Wi-Fi bands are 2.4 GHz and 5 GHz.
Each has its own strengths:
Similarly, 5G mobile networks use various GHz frequencies to deliver the ultra-fast data transmission that powers modern mobile devices.
Focusing solely on gigahertz to judge a processor's performance is a common mistake known as the "gigahertz myth."
A processor with a lower clock speed but a more efficient design (e.g., more cores, a larger cache, or better instructions per cycle) can easily outperform a processor with a higher GHz rating.
This is why comparing processors requires looking at a combination of specifications, not just the clock speed.
