How to Convert Millimeters to Gigahertz

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

Conversion Steps

  • The formula is: Frequency = Speed of Light / Wavelength
  • For example, to convert 20 mm to GHz:
  1. Convert to meters: 20 mm = 20 × 0.001 = 0.02 m
  2. Apply formula: f = 299,792,458 / 0.02 m = 1.49896e+10 Hz
  3. Convert to gigahertz: 1.49896e+10 Hz / 1.0e+9 = 5995.85 GHz

Reverse Conversion

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

  • 5995.85 GHz → λ = 299,792,458 / 1.49896e+10 Hz = 0.02 m → 20 mm
