The frequency 100 kHz equals 0.00001 seconds. This means that one cycle of 100,000 Hz takes 0.00001 seconds to complete.
To convert from kilohertz (kHz) to seconds, you find the period of one cycle, which is the reciprocal of the frequency. Since 1 kHz is 1,000 Hz, dividing 1,000 by the frequency gives the duration of each cycle in seconds. For example, for 100 kHz, the calculation is 1 / (100,000 Hz) = 0.00001 seconds.
What is 100 kHz in seconds?
100 kHz in seconds is 0.00001 seconds. This is because the period of a wave at 100 kHz is the reciprocal of the frequency, so dividing 1 by 100,000 yields the duration of each cycle in seconds.

Conversion Formula
The formula to convert khz to seconds is: period (seconds) = 1 / (frequency in Hz). Since 1 kHz equals 1,000 Hz, you multiply the khz value by 1,000 to get Hz, then take the reciprocal. For example, at 150 kHz, the calculation is 1 / (150,000) = 0.00000667 seconds. This works because frequency and period are inverses; higher frequencies mean shorter periods, and vice versa.
Conversion Example
- Convert 50 kHz to seconds:
- Multiply 50 by 1,000 to get 50,000 Hz.
- Calculate 1 / 50,000 = 0.00002 seconds.
- This is the period for 50 kHz.
- Convert 200 kHz to seconds:
- 200 * 1,000 = 200,000 Hz.
- 1 / 200,000 = 0.000005 seconds.
- Period of the wave at 200 kHz.
- Convert 75 kHz to seconds:
- 75 * 1,000 = 75,000 Hz.
- 1 / 75,000 = 0.00001333 seconds.
- Period of the wave at 75 kHz.

Conversion Definitions
khz
Khz stands for kilohertz, a unit of frequency equal to 1,000 cycles per second. It measures how many wave cycles happen in one second, often used in radio, audio, and signal processing contexts.
Seconds
Seconds are units of time representing one sixtieth of a minute. They measure duration or intervals, and in wave physics, they indicate the period or time it takes for one complete cycle of a wave to occur.
Conversion FAQs
What is the formula to convert khz to seconds?
The formula is period = 1 / (frequency in Hz). Since kilohertz is 1,000 Hz, you multiply the khz value by 1,000 to get Hz, then take the reciprocal to find the seconds per cycle.
Why does increasing frequency reduce the period?
Because frequency and period are inverses; as frequency increases, the time for each cycle decreases proportionally, resulting in a shorter period in seconds.
How precise is converting 100 kHz to seconds?
The calculation yields 0.00001 seconds exactly when using the reciprocal formula. However, rounding in display or measurement precision could slightly affect the exactness.
Can I use this conversion for audio frequencies?
Yes, audio frequencies can be converted using the same formula, but often audio frequencies are lower, so the period becomes larger and easier to interpret in seconds.
