How to Convert Megahertz 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 121 MHz to cm:
  1. Convert to hertz: 121 MHz = 121 × 1.0e+6 = 1.21e+8 Hz
  2. Apply formula: λ = 299,792,458 / 1.21e+8 Hz = 2.47762 meters
  3. Convert to centimeters: 2.47762 m / 0.01 = 3.62749e+6 cm

Reverse Conversion

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

  • 3.62749e+6 cm → f = 299,792,458 / 2.47762 m = 1.21e+8 Hz → 121 MHz
