RF Wavelength Calculator and Formula

This page provides an RF wavelength calculator. The RF wavelength formula or equation used in this calculator is also explained. This calculator determines the wavelength in meters based on the radio frequency (RF) entered, using MHz as the unit.

EXAMPLE:

• INPUT: Frequency = 850 MHz
• OUTPUT: Wavelength = 0.35 meters

RF Wavelength Formula

The following RF wavelength formula or equation is used in this RF wavelength calculator:

Wavelength (meters) = Speed of Light (m/s) / Frequency (Hz)

Since the frequency is typically entered in MHz, the formula can be expressed as:

Wavelength (meters) = 300 / Frequency (MHz)
