The frequency 20 kHz equals 0.00005 seconds.
To convert 20 kHz to seconds, you take the reciprocal of the frequency in kilohertz, which means dividing 1 by the frequency expressed in kilohertz. Since 1 kHz equals 1/1000 seconds, 20 kHz is 20,000 cycles per second. Therefore, each cycle takes 1/20000 seconds, or 0.00005 seconds.

Understanding the Conversion from kHz to Seconds
Converting from kilohertz to seconds involves understanding that frequency measures how many cycles occur in one second. Since 20 kHz means 20,000 cycles in one second, the time for one cycle is the inverse of that number, which is 1 divided by 20,000. This calculation gives the duration of a single cycle in seconds.

Conversion Formula
The formula to convert kilohertz to seconds is: seconds = 1 / (frequency in Hz). Since 1 kHz equals 1000 Hz, you multiply the kilohertz value by 1000 to get Hz, then take the reciprocal. For example, 20 kHz is 20,000 Hz, so seconds = 1 / 20,000 = 0.00005.
Conversion Example
- Convert 10 kHz:
- Step 1: 10 kHz = 10 * 1000 = 10,000 Hz
- Step 2: Calculate reciprocal: 1 / 10,000 = 0.0001 seconds
- Result: 0.0001 seconds per cycle
- Convert 50 kHz:
- Step 1: 50 kHz = 50 * 1000 = 50,000 Hz
- Step 2: Reciprocal: 1 / 50,000 = 0.00002 seconds
- Result: 0.00002 seconds per cycle
- Convert 0.5 kHz:
- Step 1: 0.5 kHz = 0.5 * 1000 = 500 Hz
- Step 2: Reciprocal: 1 / 500 = 0.002 seconds
- Result: 0.002 seconds per cycle
- Convert 100 kHz:
- Step 1: 100 kHz = 100 * 1000 = 100,000 Hz
- Step 2: Reciprocal: 1 / 100,000 = 0.00001 seconds
- Result: 0.00001 seconds per cycle

Conversion Definitions
khz
Khz stands for kilohertz, a unit of frequency equal to 1,000 cycles per second, used to measure how many wave cycles occur in one second, especially in audio, radio, and electronic signals.
seconds
Seconds is a time measurement unit representing the duration of one complete cycle of a periodic event, like a wave or signal, indicating how long it takes for one cycle to complete.
Conversion FAQs
What is the significance of converting kHz to seconds?
Converting kilohertz to seconds helps determine the time duration of one cycle in wave signals, essential for analyzing signals, designing circuits, and understanding frequency behavior in various electronic systems.
Can I convert any frequency in kHz to seconds using this method?
Yes, the method applies to all frequencies in kilohertz. Just multiply the kHz value by 1000 to get Hz, then take the reciprocal to find the seconds per cycle.
Why does the seconds value decrease as frequency increases?
Because higher frequency means more cycles per second, each cycle takes less time, so the duration in seconds decreases proportionally with increasing frequency.
