The conversion of 100 kHz to seconds results in 0.00001 seconds.
This is because frequency in kilohertz (kHz) measures how many cycles occur per thousand seconds, so to find the period in seconds, you take the reciprocal of the frequency in hertz (Hz). Since 1 kHz equals 1000 Hz, 100 kHz equals 100,000 Hz, and the period is 1 divided by that number.

Conversion Formula
The formula to convert kHz to seconds is: seconds = 1 / (frequency in Hz). Since 1 kHz equals 1000 Hz, multiply the kHz value by 1000 to get Hz, then take 1 divided by this number. This works because frequency and period are reciprocal; as frequency increases, period decreases.
For example, for 100 kHz: 100 * 1000 = 100,000 Hz. Then, 1 / 100,000 = 0.00001 seconds. This calculation shows how quickly one cycle occurs at that frequency.
Conversion Example
- Convert 50 kHz:
- Multiply 50 by 1000: 50 * 1000 = 50,000 Hz
- Calculate reciprocal: 1 / 50,000 = 0.00002 seconds
- Convert 200 kHz:
- 200 * 1000 = 200,000 Hz
- Reciprocal: 1 / 200,000 = 0.000005 seconds
- Convert 75 kHz:
- 75 * 1000 = 75,000 Hz
- Reciprocal: 1 / 75,000 = 0.00001333 seconds
- Convert 125 kHz:
- 125 * 1000 = 125,000 Hz
- Reciprocal: 1 / 125,000 = 0.000008 seconds

Conversion Definitions
kHz: Kilohertz (kHz) measures how many thousands of cycles happen per second, used to describe high-frequency signals like radio waves or electronic oscillations.
Seconds: Seconds are the base unit of time in the International System, indicating how long one cycle of a periodic event lasts, calculated as the reciprocal of frequency.
Conversion FAQs
How is the period of a 100 kHz signal calculated?
The period equals 1 divided by the frequency in hertz. For 100 kHz, which is 100,000 Hz, the period is 1 / 100,000 seconds, resulting in 0.00001 seconds per cycle.
Why does increasing frequency reduce the seconds per cycle?
Because frequency and period are inverses, as the frequency goes up, the time it takes for one cycle decreases proportionally. This relationship reflects how faster oscillations happen in less time.
Can this conversion be used for other frequencies?
Yes, the same formula applies for any frequency: seconds = 1 / (frequency in Hz). Just convert kHz to Hz by multiplying by 1000, then find the reciprocal.
What practical applications need this conversion?
This conversion is essential in signal processing, electronics, and radio communications to understand how long signals last or how fast they oscillate.
