RF to Wavelength Calculator
About This Calculator
The ITU RF to Wavelength Calculator is designed to simplify the calculation of wavelength for a given frequency. By using the formula \( \lambda = \frac{c}{f} \), where \( c \) is the speed of light, this tool quickly converts radio frequencies to their corresponding wavelengths. It also provides detailed information on the frequency bands and their applications, making it an essential reference for engineers, students, and enthusiasts in the field of telecommunications and radio systems.
Wavelength Formula
\( \lambda = \frac{c}{f} \)
Where:
- \( \lambda \) (lambda): Wavelength in meters
- c: Speed of light (299,792,458 m/s)
- f: Frequency in Hertz

Example Calculations with Unit Conversion
-
Calculate the wavelength of 1500 kHz:
- Convert frequency to Hz: \( 1500 \text{ kHz} = 1,500,000 \text{ Hz} \)
- \( \lambda = \frac{c}{f} = \frac{299,792,458 \text{ m/s}}{1,500,000 \text{ Hz}} \approx 199.86 \text{ meters} \)
-
Calculate the wavelength of 5 GHz in centimeters:
- Convert frequency to Hz: \( 5 \text{ GHz} = 5,000,000,000 \text{ Hz} \)
- \( \lambda = \frac{c}{f} \)
- \(= \frac{299,792,458 \text{ m/s}}{5,000,000,000 \text{ Hz}} \approx 0.0599585 \text{ meters} \)
- \(= 5.99585 \text{ centimeters} \)
