Understanding Kilohertz and Hertz
Kilohertz (kHz) and Hertz (Hz) are units of frequency measurement. Frequency refers to the number of occurrences of a repeating event within a specific time frame. In the context of electrical signals and electromagnetic waves, frequency measures the number of cycles completed per second.
1 kilohertz (kHz) is equal to 1,000 hertz (Hz).
Conversion Formula
To convert kilohertz to hertz, simply multiply the kilohertz value by 1,000.
Frequency (Hz) = Frequency (kHz) x 1,000
Practical Applications of Kilohertz and Hertz
Kilohertz (kHz)
- Audio signals (e.g., telephone conversations, music recording)
- Radio frequencies (e.g., AM radio broadcasts)
- Ultrasonic waves (e.g., medical imaging, cleaning)
Hertz (Hz)
- Electric power systems (e.g., alternating current at 60 Hz in North America)
- Computer clock speeds (e.g., processor frequency of 3.6 GHz)
- Electromagnetic waves (e.g., visible light, microwaves, X-rays)
Table of Common Frequency Ranges
| Frequency Range | Unit | Applications |
|---|---|---|
| 1-20 kHz | kHz | Audio signals |
| 20-200 kHz | kHz | Radio frequencies (AM) |
| 200-2,000 kHz | kHz | Ultrasonic waves |
| 2,000-20,000 Hz | Hz | Audio signals |
| 20-200 Hz | Hz | Electric power systems |
| 200-2,000 Hz | Hz | Computer clock speeds |
| 2,000-20,000 GHz | Hz | Electromagnetic waves (visible light) |
How to Convert Kilo Hertz to Hertz in Different Scenarios
Example 1: Audio Signal
An audio signal with a frequency of 10 kHz needs to be converted to hertz.
- Formula: Frequency (Hz) = Frequency (kHz) x 1,000
- Conversion: 10 kHz x 1,000 = 10,000 Hz
Example 2: Radio Frequency
A radio frequency of 150 kHz needs to be converted to hertz.
- Formula: Frequency (Hz) = Frequency (kHz) x 1,000
- Conversion: 150 kHz x 1,000 = 150,000 Hz
Example 3: Ultrasonic Waves
Ultrasonic waves with a frequency of 2.5 MHz need to be converted to hertz.
- Note: Megahertz (MHz) is a million hertz.
- Formula: Frequency (Hz) = Frequency (MHz) x 1,000,000
- Conversion: 2.5 MHz x 1,000,000 = 2,500,000 Hz
Table of Conversion Values
| Kilohertz | Hertz |
|---|---|
| 1 | 1,000 |
| 2 | 2,000 |
| 5 | 5,000 |
| 10 | 10,000 |
| 15 | 15,000 |
| 20 | 20,000 |
