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 90 GHz to mm:
  1. Convert to hertz: 90 GHz = 90 × 1.0e+9 = 9.0e+10 Hz
  2. Apply formula: λ = 299,792,458 / 9.0e+10 Hz = 0.00333103 meters
  3. Convert to millimeters: 0.00333103 m / 0.001 = 26981.3 mm

Reverse Conversion

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

  • 26981.3 mm → f = 299,792,458 / 0.00333103 m = 9.0e+10 Hz → 90 GHz
