One kilohertz is equivalent to 1,000 cycles per second. It is used in radio broadcasting, audio signals, and many other fields. For instance, the human hearing range is approximately from 20 Hz to 20 kHz.
One gigahertz is equivalent to 1,000,000,000 (or 109) cycles per second. It is widely referenced in computing, as the clock speed of CPUs is commonly measured in GHz. This refers to how many cycles a CPU can execute in a second. For instance, a 3 GHz processor performs 3 billion cycles per second.
1kHz = 0.000001GHz
or
1GHz = 1000000kHz
f(GHz) = f(kHz) / 1000000
Example – Convert 3 kilohertz to gigahertz:
Ans. f(GHz) = 3kHz / 1000000 = 0.000003GHz
| Kilohertz (kHz) | Gigahertz (GHz) |
| 0 kHz | 0 GHz |
| 1 kHz | 0.000001 GHz |
| 10 kHz | 0.00001 GHz |
| 100 kHz | 0.0001 GHz |
| 1000 kHz | 0.001 GHz |
| 10000 kHz | 0.01 GHz |
| 100000 kHz | 0.1 GHz |
| 1000000 kHz | 1 GHz |
GHz is higher than kHz. 1 GHz is equivalent to 1,000,000 kHz.
1 kHz is equal to 1,000 Hertz (Hz).
1 GHz is equal to 1,000,000,000 Hertz (Hz) or 1 billion Hertz.
The primary difference is in scale. 1 GHz represents 1 billion cycles per second, while 1 kHz represents 1 thousand cycles per second. Specifically, 1 GHz is 1 million times greater than 1 kHz.
n the context of computing and processors, 1 GHz is considered a benchmark for frequency, but with modern advancements, there are now processors that operate at frequencies much higher than 1 GHz. In terms of electromagnetic spectrum, 1 GHz falls under the microwave frequency range, which is higher than radio frequencies but lower than infrared frequencies.
In the context of processor speeds, the higher the GHz, the faster the processor can execute tasks, given all other factors are constant. As of my last update in September 2021, there are consumer CPUs with frequencies above 5 GHz. However, it's important to note that GHz isn't the sole factor determining performance; architecture, number of cores, and other factors are also crucial.
G networks operate on a range of frequencies. Initially, most 5G deployments were in the sub-6 GHz range, but there's also a high-band or millimeter-wave 5G that typically uses frequencies in the 24 GHz to 100 GHz range. The exact frequencies might vary based on the country and the specific spectrum allocated for 5G.
