The frequency 20 kHz equals 0.05 milliseconds (ms).
This means that a wave vibrating at 20,000 times per second completes each cycle in 0.05 ms, because the period (time for one cycle) is the reciprocal of frequency. So, dividing 1 second by 20,000 gives the cycle duration in milliseconds.
What is the period of 20 kHz in milliseconds?
The period of a 20 kHz signal is 0.05 ms. This is because frequency and period are inversely related; the period is calculated by dividing 1 second (1000 ms) by the frequency in Hz. Therefore, for 20,000 Hz, the period is 1000 / 20,000 = 0.05 ms.

Conversion Formula
The conversion from khz to ms uses the formula: period (ms) = 1000 / frequency (kHz). Because 1 kHz equals 1000 Hz, the period in milliseconds is the time for one cycle, found by dividing 1000 milliseconds by the frequency in kilohertz. For example, at 20 kHz, 1000 / 20 = 50 ms.
Conversion Example
- Convert 10 kHz:
- Apply formula: 1000 / 10 = 100 ms
- The wave completes a cycle in 100 milliseconds.
- Convert 50 kHz:
- Apply formula: 1000 / 50 = 20 ms
- Each cycle lasts 20 milliseconds.
- Convert 5 kHz:
- Apply formula: 1000 / 5 = 200 ms
- The period of this wave is 200 milliseconds per cycle.
- Convert 25 kHz:
- Apply formula: 1000 / 25 = 40 ms
- It takes 40 milliseconds for one cycle.
- Convert 1 kHz:
- Apply formula: 1000 / 1 = 1000 ms
- The wave completes a cycle in a full second.

Conversion Definitions
khz
Khz (kilohertz) measures the number of cycles or vibrations per thousand seconds, representing how frequently a wave oscillates. It is a unit of frequency used mainly in radio, audio, and signal processing contexts to describe how often events occur per second.
ms
Ms (milliseconds) is a unit of time equal to one thousandth of a second, used to measure durations, delays, or periods of oscillations. It helps to quantify how long specific events, such as wave cycles, last in a precise, small time scale.
Conversion FAQs
What does converting 20 kHz to ms tell me about the wave?
Converting 20 kHz to ms reveals how long it takes for one cycle of that frequency to complete. It helps in understanding how quickly the wave oscillates, which impacts applications like audio processing, radio transmission, and signal timing.
Why is the period decreasing as frequency increases?
Because period and frequency are inversely related, higher frequencies mean waves oscillate faster, reducing the time for each cycle. So, as frequency grows, the period in ms gets smaller, illustrating a faster oscillation.
How accurate is the conversion in the calculator?
The calculator uses the exact formula: 1000 divided by the input frequency in kHz, providing results accurate to four decimal places. Minor rounding may occur, but generally, the calculation reflects precise period durations for the given frequency.
Can I use this conversion for frequencies above 100 kHz?
Yes, the formula applies universally: period (ms) = 1000 / frequency (kHz). For very high frequencies, the period becomes very small, but the calculation remains valid, offering quick estimates for frequencies well above 20 kHz.
Is there a way to convert ms back to kHz?
Yes, simply invert the formula: frequency (kHz) = 1000 / period (ms). This allows you to find the frequency based on a known period in milliseconds, useful for designing or analyzing signals.
