Quick answer
Frequency and wavelength are linked by wave speed: wavelength equals speed divided by frequency. For electromagnetic waves in vacuum that speed is 299,792,458 m/s, so a 100 MHz FM signal has a wavelength of about 3 metres. One kilohertz is 1,000 Hz, one megahertz a million and one gigahertz a billion.
| Hertz (Hz) | 1 |
| Kilohertz (kHz) | 0.001 |
| Megahertz (MHz) | 0.000001 |
| Gigahertz (GHz) | 1.000000e-9 |
| Terahertz (THz) | 1.000000e-12 |
About the Frequency Wavelength Converter
Frequency measures how many cycles of a wave occur each second, expressed in hertz. Radio, sound and light are all described by their frequency.
This converter moves between hertz, kilohertz, megahertz, gigahertz and terahertz.
Frequently Asked Questions
What is frequency?
⌄
Frequency is the number of wave cycles that pass a point each second, measured in hertz (Hz).
How many hertz are in a megahertz?
⌄
One megahertz equals 1,000,000 hertz; one gigahertz equals 1,000 megahertz.
How are frequency and wavelength related?
⌄
They are inversely related: for a given wave speed, higher frequency means shorter wavelength.
