This online ITU Radio Frequency to Wavelength Conversion tool makes it easy to turn a given frequency into its corresponding wavelength. You enter the frequency value in MHz, click Convert, and you immediately get the wavelength in meters using the formula λ = 300 / f.
Frequency–Wavelength Converter
ITU Regions Overview
The International Telecommunication Union (ITU) divides the world into three regions for spectrum management. Each region has distinct allocation rules and typical applications.
Region 1
Europe, Africa, the Middle East, Russia, and Mongolia. Key uses include broadcast services and fixed/mobile communications.
Region 2
North and South America, Greenland, and some Pacific islands. Focused on aviation, maritime, and mobile services.
Region 3
Asia (excluding parts in Region 1), Australasia, and Pacific islands. Rapid growth in mobile and satellite communications.
Basics of Radio Waves
Radio waves are part of the electromagnetic spectrum used in wireless communication. Their frequency and wavelength are related by:
λ = c / f
- λ – Wavelength (meters)
- c – Speed of light (299,792,458 m/s)
- f – Frequency (Hz)
Common Bands:
- LF (30–300 kHz): Ground-wave propagation.
- MF (300 kHz–3 MHz): AM radio.
- HF (3–30 MHz): Shortwave and long-distance.
- VHF (30–300 MHz): FM radio, TV, aviation.
- UHF (300 MHz–3 GHz): Mobile, Wi‑Fi, TV.
Frequently Asked Questions
The ITU divides the globe into three regions to manage spectrum allocation. Different regions have tailored rules to suit geographic and technical requirements.
No. Wavelength calculation is purely physical (λ = c/f). Region selection only influences allocation and typical use cases.
Select based on your location or intended service area: Europe/Africa (Region 1), Americas (Region 2), Asia-Pacific (Region 3).
