How to Convert Micrometers to Terahertz

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 2.1 × 107 µm to THz:
  1. Convert to meters: 2.1e+7 µm = 2.1e+7 × 1.0e-6 = 21 m
  2. Apply formula: f = 299,792,458 / 21 m = 1.42758e+7 Hz
  3. Convert to terahertz: 1.42758e+7 Hz / 1.0e+12 = 6.29564e+9 THz

Reverse Conversion

To convert terahertz back to micrometers, use λ = c / f:

  • 6.29564e+9 THz → λ = 299,792,458 / 1.42758e+7 Hz = 21 m → 2.1e+7 µm
