The frequency 20 kHz corresponds to 0.00005 seconds per cycle.
Since frequency measures how many cycles occur per second, to find the duration of one cycle in seconds, divide 1 second by the frequency in Hz. For 20 kHz, which is 20,000 Hz, 1 divided by 20,000 gives the amount of seconds per cycle.
Conversion Result
20 kHz equals 0.00005 seconds.

Conversion Formula
The formula to convert kilohertz to seconds is: seconds = 1 / (frequency in Hz). Since 1 kHz equals 1000 Hz, multiply the kHz value by 1000 to get Hz, then take the reciprocal. For example, for 20 kHz: 1 / (20 * 1000) = 0.00005 seconds. This works because frequency and period are inverse of each other.
Conversion Example
- Convert 10 kHz:
- Multiply 10 by 1000: 10 * 1000 = 10,000 Hz
- Calculate reciprocal: 1 / 10,000 = 0.0001 seconds
- Result: 10 kHz equals 0.0001 seconds
- Convert 50 kHz:
- 50 * 1000 = 50,000 Hz
- 1 / 50,000 = 0.00002 seconds
- Result: 50 kHz equals 0.00002 seconds
- Convert 5 kHz:
- 5 * 1000 = 5,000 Hz
- 1 / 5,000 = 0.0002 seconds
- Result: 5 kHz equals 0.0002 seconds

Conversion Definitions
kHz: Kilohertz (kHz) is a frequency unit equal to 1,000 cycles per second, used to measure how many oscillations happen in a second, often in radio, audio, and electronic signals.
Seconds: Seconds are a basic time unit representing the duration of 9,192,631,770 periods of radiation from a cesium-133 atom, used to measure how long an event lasts or the period of a cycle.
Conversion FAQs
What does it mean when 20 kHz equals 0.00005 seconds?
This means that each cycle of a 20 kHz signal lasts 0.00005 seconds, indicating how quickly the wave oscillates. A higher frequency results in a shorter period or cycle duration.
Can I use the same formula to convert any kHz value to seconds?
Yes, the same formula applies: seconds = 1 / (kHz * 1000). It works for any frequency because it calculates the time for a single cycle inversely proportional to the frequency in Hz.
Why is the result so small when converting 20 kHz?
Because 20 kHz is a high frequency, each cycle occurs very quickly, resulting in a very short duration in seconds. The reciprocal of high numbers is small, leading to tiny cycle periods.
What is the significance of converting kHz to seconds?
Converting frequency to time helps in understanding the duration of oscillations, designing electronic circuits, analyzing signals, and synchronizing timing in various electronic and audio applications.
How accurate is the conversion for practical purposes?
The conversion is precise to the decimal places shown, which is sufficient for most engineering, audio, and scientific tasks, unless extremely high precision is required, then more decimal places or specialized tools might be necessary.
