0.00005 seconds is the result of converting 20 kHz to seconds.
To convert 20 kilohertz to seconds, we need to understand that frequency in kHz measures cycles per thousand seconds. Since 1 kHz equals 1,000 cycles per second, 20 kHz is 20,000 cycles per second. The period, or duration of one cycle, is the reciprocal of frequency: 1 divided by 20,000, giving 0.00005 seconds per cycle.

Conversion Formula
The conversion from khz to seconds involves taking the reciprocal of the frequency in hertz. Since 1 kHz equals 1,000 Hz, to find the period (seconds per cycle), we divide 1 by the total cycles per second. For example, a frequency of 20 kHz equals 20,000 Hz, so the period is 1 divided by 20,000, which results in 0.00005 seconds. This formula works because frequency and period are inverse; as one increases, the other decreases.
Conversion Example
- Convert 10 kHz:
- Frequency in Hz: 10,000 Hz (10 x 1,000)
- Period = 1 / 10,000 = 0.0001 seconds
- Convert 50 kHz:
- Frequency in Hz: 50,000 Hz
- Period = 1 / 50,000 = 0.00002 seconds
- Convert 5 kHz:
- Frequency in Hz: 5,000 Hz
- Period = 1 / 5,000 = 0.0002 seconds
- Convert 1.5 kHz:
- Frequency in Hz: 1,500 Hz
- Period = 1 / 1,500 ≈ 0.0006667 seconds
- Convert 30 kHz:
- Frequency in Hz: 30,000 Hz
- Period = 1 / 30,000 ≈ 0.0000333 seconds

Conversion Definitions
khz
Khz (kilohertz) measures how many thousands of complete wave cycles occur every second, acting as a unit of frequency that indicates how fast a periodic event repeats over time.
seconds
Seconds are a time unit that quantifies the duration of an event, representing how long it takes for one cycle of a periodic phenomenon to complete, inversely related to frequency.
Conversion FAQs
How do I know if my 20 kHz signal is fast or slow?
The speed of a 20 kHz signal is considered quite high, especially in audio or radio contexts, because it completes 20,000 cycles each second, which is beyond human hearing and indicates a rapid oscillation.
Is the period of 20 kHz suitable for audio applications?
No, 20 kHz is at the upper limit of human hearing, so signals at this frequency are often used in audio testing or high-frequency electronics, but are not typical for everyday sound recordings.
What happens to the period if I increase the frequency?
As the frequency increases, the period decreases, meaning each cycle takes less time; for example, doubling the frequency halves the seconds per cycle, making the oscillations faster.
Can I convert any kHz value to seconds with this method?
Yes, as long as you remember that seconds per cycle equals 1 divided by (frequency in kHz times 1000), this method applies universally for all frequency values.
Why is the reciprocal used for conversion?
The reciprocal is used because frequency and period are inversely proportional: higher frequency means shorter periods, and vice versa, making the reciprocal the natural mathematical operation for conversion.
