The frequency 20 kHz equals 0.05 milliseconds per cycle.
Since 20 kHz means 20,000 cycles per second, each cycle takes 1 divided by 20,000 seconds, which is 0.00005 seconds or 0.05 ms. This shows how quickly the wave repeats, with each cycle lasting just 0.05 milliseconds.

Conversion Formula
The formula to convert kilohertz (kHz) to milliseconds (ms) is: 1 divided by (frequency in kHz times 1000). This is because one cycle duration (period) in seconds equals 1 divided by the frequency in Hertz, and 1 kHz equals 1000 Hz. So, period in ms = 1 / (frequency * 1000).
For example, for 20 kHz: 1 / (20 * 1000) = 1 / 20000 = 0.00005 seconds, which equals 0.05 ms. This calculation shows how the period gets smaller as frequency increases.
Conversion Example
- Convert 10 kHz:
- Apply formula: 1 / (10 * 1000) = 1 / 10000
- Calculate: 0.0001 seconds
- Convert to ms: 0.0001 * 1000 = 0.1 ms
- Result: 10 kHz equals 0.1 ms
- Convert 50 kHz:
- Apply formula: 1 / (50 * 1000) = 1 / 50000
- Calculate: 0.00002 seconds
- Convert to ms: 0.00002 * 1000 = 0.02 ms
- Result: 50 kHz equals 0.02 ms
- Convert 5 kHz:
- Apply formula: 1 / (5 * 1000) = 1 / 5000
- Calculate: 0.0002 seconds
- Convert to ms: 0.0002 * 1000 = 0.2 ms
- Result: 5 kHz equals 0.2 ms

Conversion Definitions
khz
khz, or kilohertz, measures frequency equal to 1,000 cycles per second, indicating how many wave cycles occur every second, used often in audio, radio, and signal processing to specify the speed of oscillations.
ms
ms, or milliseconds, indicates a unit of time equal to one-thousandth of a second, used to measure very short durations like wave periods, delays, or pulse widths in electronic and signal contexts.
Conversion FAQs
How do I interpret the ms value when converting from 20 kHz?
The ms value shows the time for one complete wave cycle at the frequency. For 20 kHz, this is 0.05 ms, meaning each wave repeats every 0.05 milliseconds, which is very fast and typical for high-frequency signals.
Is the conversion the same for all frequencies?
No, the formula applies to all frequencies; as the frequency increases, the period in ms decreases proportionally. For example, at 10 kHz, the cycle lasts 0.1 ms, but at 50 kHz, it drops to 0.02 ms.
What practical uses are there for knowing the period in ms for a given frequency?
Knowing the cycle duration helps in designing circuits, understanding signal timings, or adjusting audio and radio equipment where precise timing of wave cycles impacts performance and clarity.
Can I convert any frequency from kHz to ms using this method?
Yes, the same formula applies: period in ms = 1 / (frequency in kHz * 1000). It works for all frequencies, allowing quick calculation regardless of the value.
Why is the period so short at higher frequencies like 20 kHz?
Because higher frequencies mean waves repeat faster, each cycle takes less time. At 20 kHz, a wave completes in just 0.05 ms, making signals at these frequencies very rapid and hard to perceive visually.
