Samantha NicoleThe frequency 1 kHz corresponds to approximately 0.343 meters. This means a wave oscillating at that frequency has a wavelength around this length.
To convert 1 kilohertz (kHz) to meters, we need to understand the relationship between frequency and wavelength. Since wavelength equals the speed of light divided by frequency, this calculation involves dividing 299,792,458 m/sec by the frequency in Hz, where 1 kHz equals 1000 Hz.
Wave Length from 1 kHz
At 1 kHz, the wavelength is obtained by dividing the speed of light (about 299,792,458 meters per second) by 1000 Hz. So, the wavelength in meters is approximately 299,792.458 / 1000 = 299.792 meters. But because of the approximation, the exact value is about 0.343 meters if considering other wave types like sound, but for light, it’s about 299.8 meters.

Conversion Formula
The formula to convert frequency in kHz to wavelength in meters is: wavelength = speed of light / (frequency in Hz). Since 1 kHz equals 1000 Hz, you multiply the input by 1000 to get Hz. The speed of light is approximately 299,792,458 meters per second. By dividing this speed by the frequency in Hz, you get the wavelength in meters.
For example, at 1 kHz: wavelength = 299,792,458 / (1 * 1000) = 299,792.458 meters. For 10 kHz: wavelength = 299,792,458 / (10 * 1000) = 29,979.2458 meters. The division inversely relates frequency to wavelength, meaning as frequency increases, wavelength decreases.
Conversion Example
- Convert 2 kHz:
- Multiply 2 by 1000 to get 2000 Hz.
- Divide 299,792,458 by 2000.
- Result is about 149,896.229 meters.
- Convert 0.5 kHz:
- Multiply 0.5 by 1000 to get 500 Hz.
- Divide 299,792,458 by 500.
- Result is approximately 599,584.916 meters.
- Convert 5 kHz:
- Multiply 5 by 1000 to get 5000 Hz.
- Divide 299,792,458 by 5000.
- Result is about 59,958.491 meters.
- Convert 10 kHz:
- Multiply 10 by 1000 to get 10,000 Hz.
- Divide 299,792,458 by 10,000.
- Result is approximately 29,979.2458 meters.

Conversion Definitions
khz
Khz is a unit of frequency equal to 1000 cycles per second, used mainly to measure electromagnetic and sound waves. It indicates how many wave cycles pass a point in one second, with higher values meaning faster oscillations and shorter wavelengths.
meters
Meters is a length measurement unit in the metric system, used to quantify distance or wavelength in various physical phenomena. It defines the space between two points and is the standard unit for scientific measurements involving wave lengths.
Conversion FAQs
How does the wavelength change when I increase the frequency from 1 kHz to 2 kHz?
As the frequency doubles from 1 kHz to 2 kHz, the wavelength halves. Since wavelength is inversely proportional to frequency, doubling the frequency results in a wavelength reduction by half, from about 0.343 meters to approximately 0.172 meters.
Can I use this to find the wavelength of radio signals at 100 MHz?
Yes, but you need to convert 100 MHz into kHz first, which is 100,000 kHz. Then, applying the same formula, divide the speed of light by 100,000,000 Hz to get the wavelength, which would be about 3 meters for radio waves at 100 MHz.
What affects the wavelength of a wave in different mediums?
The wavelength depends on both the wave’s frequency and the speed of wave propagation in the medium. In different materials, light or sound may travel faster or slower, altering the wavelength while the frequency remains unchanged.
Why is the wavelength for 1 kHz sound much shorter than for 1 kHz light?
This is because sound waves and light waves travel at different speeds in the same medium, with light moving at about 299,792,458 meters/sec, while sound has much slower velocity. As a result, their wavelengths at the same frequency differ vastly.
