The frequency 20 kHz equals 0.00005 seconds.

Since 20 kHz means 20,000 cycles per second, to find the duration of one cycle in seconds, you divide 1 by 20,000. That gives 0.00005 seconds per cycle, which is how long each wave lasts at this frequency.

Conversion Result

One cycle at 20 kHz takes approximately 0.00005 seconds.

Conversion Formula

The formula to convert khz to seconds is: seconds = 1 / (frequency in khz * 1000). This works becuase 1 kilohertz equals 1000 cycles per second; so, for any frequency, the period of one cycle is the reciprocal of the total cycles per second. For example, at 20 khz, 1 / (20 * 1000) = 0.00005 seconds.

Conversion Example

• Convert 10 khz: 1 / (10 * 1000) = 0.0001 seconds.
  • Frequency is 10,000 Hz.
  • Calculate 1 / 10,000.
  • Result is 0.0001 seconds.
• Convert 50 khz: 1 / (50 * 1000) = 0.00002 seconds.
  • Frequency is 50,000 Hz.
  • Calculate 1 / 50,000.
  • Result is 0.00002 seconds.
• Convert 5 khz: 1 / (5 * 1000) = 0.0002 seconds.
  • Frequency is 5000 Hz.
  • Calculate 1 / 5000.
  • Result is 0.0002 seconds.
• Convert 100 khz: 1 / (100 * 1000) = 0.00001 seconds.
  • Frequency is 100,000 Hz.
  • Calculate 1 / 100,000.
  • Result is 0.00001 seconds.
• Convert 1 khz: 1 / (1 * 1000) = 0.001 seconds.
  • Frequency is 1000 Hz.
  • Calculate 1 / 1000.
  • Result is 0.001 seconds.

Conversion Definitions

khz: Kilohertz (kHz) measures the number of cycles or oscillations per thousand seconds. It is used to describe frequencies of sound waves, radio signals, and electronic signals, indicating how rapidly they repeat within a second.

seconds: Seconds (s) are a basic unit of time measurement, representing the duration of one complete cycle of a wave or event. It quantifies how long an occurrence or oscillation lasts, serving as the standard for timing in science and daily life.

Conversion FAQs

How do I convert 20 kHz to seconds manually?

To convert 20 kHz to seconds, divide 1 by the frequency in Hz. Since 1 kHz equals 1000 Hz, multiply 20 by 1000 to get 20000 Hz. Then, calculate 1 / 20000, which results in 0.00005 seconds per cycle.

Why is the result of 20 kHz in seconds so small?

Because higher frequencies mean shorter periods, and at 20 kHz, each cycle lasts just 0.00005 seconds. This tiny duration occurs because the wave oscillates rapidly, reducing the time for a single cycle significantly.

What happens if I input negative frequency values?

Negative frequency values are not physically meaningful in this context, and the calculation would produce a negative or nonsensical result. Frequencies should be positive numbers, representing cycles per second.

Is the conversion accurate for decimal frequencies like 20.5 kHz?

Yes, the formula and calculator handle decimal frequencies accurately. For 20.5 kHz, the period is 1 / (20.5 * 1000) = approximately 0.00004878 seconds, which the tool computes precisely.

Can I convert from seconds back to kHz using this tool?

No, this tool is designed to convert from kHz to seconds. To convert seconds to kHz, you would invert the process, calculating 1 / seconds and dividing by 1000.
