How to Convert Megahertz to Meters

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 21 MHz to m:
  1. Convert to hertz: 21 MHz = 21 × 1.0e+6 = 2.1e+7 Hz
  2. Apply formula: λ = 299,792,458 / 2.1e+7 Hz = 14.2758 meters
  3. Result: 6295.64 m

Reverse Conversion

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

  • 6295.64 m → f = 299,792,458 / 14.2758 m = 2.1e+7 Hz → 21 MHz
