How to Convert Gigahertz to Millimeters

Wavelength and frequency are inversely related through the speed of light. The formula is: λ = c / f, where λ is the wavelength, c = 299,792,458 m/s (speed of light in vacuum), and f is the frequency.

Conversion Steps

  • The formula is: Wavelength = Speed of Light / Frequency
  • For example, to convert 1 GHz to mm:
  1. Convert to hertz: 1 GHz = 1 × 1.0e+9 = 1.0e+9 Hz
  2. Apply formula: λ = 299,792,458 / 1.0e+9 Hz = 0.299792 meters
  3. Convert to millimeters: 0.299792 m / 0.001 = 299.792 mm

Reverse Conversion

To convert millimeters back to gigahertz, use f = c / λ:

  • 299.792 mm → f = 299,792,458 / 0.299792 m = 1.0e+9 Hz → 1 GHz
