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 4 × 107 MHz to cm:
  1. Convert to hertz: 4.0e+7 MHz = 4.0e+7 × 1.0e+6 = 4.0e+13 Hz
  2. Apply formula: λ = 299,792,458 / 4.0e+13 Hz = 7.49481e-6 meters
  3. Convert to centimeters: 7.49481e-6 m / 0.01 = 1.19917e+12 cm

Reverse Conversion

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

  • 1.19917e+12 cm → f = 299,792,458 / 7.49481e-6 m = 4.0e+13 Hz → 4.0e+7 MHz
