The conversion of 20 kHz to seconds equals 0.00005 seconds.
This is because 20 kilohertz means 20,000 cycles per second. To find the duration of one cycle, you take the reciprocal of the frequency, which is 1 divided by 20,000, resulting in 0.00005 seconds. So, each cycle lasts this long.
Conversion Result
20 kHz corresponds to 0.00005 seconds per cycle, which means each wave cycle takes that much time to complete.

Conversion Formula
The formula to convert kilohertz to seconds involves taking the reciprocal of the frequency in hertz. Since 1 kilohertz equals 1000 hertz, dividing 1 by (frequency in khz multiplied by 1000) gives the duration of one cycle in seconds. This works because frequency is cycles per second, so its reciprocal is seconds per cycle.
For example, at 20 kHz, multiply 20 by 1000 to get 20,000 Hz. Then, 1 divided by 20,000 equals 0.00005 seconds per cycle, which is the length of one wave cycle at this frequency.
Conversion Example
- Converting 10 kHz:
- Multiply 10 by 1000: 10 * 1000 = 10,000 Hz
- Calculate reciprocal: 1 / 10,000 = 0.0001 seconds
- Converting 50 kHz:
- Multiply 50 by 1000: 50 * 1000 = 50,000 Hz
- Calculate reciprocal: 1 / 50,000 = 0.00002 seconds
- Converting 5 kHz:
- Multiply 5 by 1000: 5 * 1000 = 5,000 Hz
- Calculate reciprocal: 1 / 5,000 = 0.0002 seconds
- Converting 100 kHz:
- Multiply 100 by 1000: 100 * 1000 = 100,000 Hz
- Calculate reciprocal: 1 / 100,000 = 0.00001 seconds
- Converting 2 kHz:
- Multiply 2 by 1000: 2 * 1000 = 2,000 Hz
- Calculate reciprocal: 1 / 2,000 = 0.0005 seconds

Conversion Definitions
khz (kilohertz) is a unit of frequency equal to 1,000 cycles per second, used to measure how often a wave repeats each second. Seconds are a unit of time representing the duration of one complete cycle of a wave, indicating how long it takes for one repetition to occur.
Conversion FAQs
What does 20 kHz mean in terms of wave cycles?
20 kHz indicates 20,000 wave cycles occur each second. It measures how many times a wave pattern repeats in one second, so a higher kHz means faster oscillations and shorter cycle durations.
How accurate is the conversion from kHz to seconds?
The conversion relies on the reciprocal calculation and assumes ideal waveforms. Minor inaccuracies may happen due to measurement limitations or signal distortions, but generally, the reciprocal method provides precise cycle durations for frequencies like 20 kHz.
Can I use this conversion for other frequencies?
Yes, the same reciprocal formula applies for any frequency measured in kHz. Just multiply the frequency in kHz by 1000 to get Hz, then take 1 divided by that value to find the seconds per cycle.
What is the significance of knowing the seconds per cycle?
This helps in understanding wave behavior, designing electronic circuits, or analyzing signals, as it tells you how long each wave takes to complete, which is vital for timing calculations and signal processing.
How do I convert 50 kHz to seconds?
Multiply 50 by 1000 to get 50,000 Hz, then take 1 divided by 50,000 to find 0.00002 seconds per cycle. This process applies to any frequency in kilohertz.
