Kilohertz (kHz)
Definition: A kilohertz (symbol: kHz) is a multiple of the hertz, equaling 1,000 cycles per second.
History/origin: As early radio technology developed in the early 20th century, scientists needed a larger unit to describe the higher frequencies used for AM (Amplitude Modulation) broadcasting.
Current use: Kilohertz are commonly used to measure AM radio broadcasts, audio sample rates (like CDs at 44.1 kHz), and the frequency of ultrasound devices.
Hertz (Hz)
Definition: The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI). It is defined as one cycle or event per second.
History/origin: The unit is named after the German physicist Heinrich Hertz, who made important scientific contributions to the study of electromagnetism in the late 19th century.
Current use: Hertz is the fundamental unit used to measure the frequency of sound waves, electrical currents (like the 50/60 Hz AC power in your home), and all electromagnetic radiation.
Kilohertz (kHz) to Hertz (Hz) Conversion Table
| Kilohertz (kHz) [khz] | Hertz (Hz) [hz] |
|---|---|
| 0.01 khz | 10 hz |
| 0.1 khz | 100 hz |
| 1 khz | 1000 hz |
| 2 khz | 2000 hz |
| 3 khz | 3000 hz |
| 5 khz | 5000 hz |
| 10 khz | 10000 hz |
| 20 khz | 20000 hz |
| 50 khz | 50000 hz |
| 100 khz | 100000 hz |
| 1000 khz | 1000000 hz |
How to Convert Kilohertz (kHz) to Hertz (Hz)
1 khz = 1000 hz
1 hz = 0.001 khz
Example: convert 15 khz to hz:
15 khz = 15 × 1000 hz = 15000 hz
Did You Know?
- AM radio stations broadcast their signals in Kilohertz (kHz). For example, a station at "790 on the AM dial" is broadcasting at exactly 790 kHz.
- Did you know? A healthy young human ear can hear sound frequencies ranging from 20 Hertz (very low bass) up to 20,000 Hertz (very high pitch).
