RF Frequency to Wavelength Calculator
Convert radio frequency to wavelength for antenna design and RF engineering.
Supports Hz through GHz and metric/imperial.
Wavelength
Frequency and Wavelength are inversely related through the speed of light:
λ = c / f
Where:
- λ = wavelength
- c = speed of light (299,792,458 m/s)
- f = frequency
Common RF bands:
| Band | Frequency | Wavelength |
|---|---|---|
| AM Radio | 530–1700 kHz | 176–565 m |
| FM Radio | 88–108 MHz | 2.8–3.4 m |
| Wi-Fi 2.4 GHz | 2,400 MHz | 12.5 cm |
| Wi-Fi 5 GHz | 5,800 MHz | 5.2 cm |
| Cellular 5G | 28,000 MHz | 10.7 mm |
Antenna design: A half-wave dipole antenna length = λ/2. A quarter-wave antenna = λ/4.
