Free-Space Wavelength

Free-space wavelength calculator using λ = c / f and f = c / λ (with c = 299,792,458 m/s).

RF Tools • Wavelength • Frequency

Solve for λ (meters)

Frequency f (MHz) Example: 2400 MHz = 2.4 GHz

—

Enter f (MHz) and calculate.

Wavelength λ (m) Example: 0.125 m = 12.5 cm

—

Enter λ (m) and calculate.
