How to Convert Gigahertz to Centimeters

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 cm:
  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 centimeters: 0.00333103 m / 0.01 = 2698.13 cm

Reverse Conversion

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

  • 2698.13 cm → f = 299,792,458 / 0.00333103 m = 9.0e+10 Hz → 90 GHz
