Reciprocal Centimeters To Gigahertz Converter
Reverse Conversion
How This Converter Works
Convert between Reciprocal Centimeters (cm⁻¹) and Gigahertz (GHz). Select either direction to convert directly.
Formula or rule
Gigahertz = Reciprocal Centimeters * 29.9792458; Reciprocal Centimeters = Gigahertz / 29.9792458
Example
- Input
- 1 cm⁻¹
- Calculation
- 1 * 29.9792458 = 29.9792458
- Result
- 29.9792458 GHz
Notes
Spectroscopic wavenumber is reciprocal wavelength, conventionally expressed in cm⁻¹. The frequency and photon-energy equivalents here assume vacuum propagation and use ν = cṽ and E = hcṽ with exact SI values of c, h, and the elementary charge.
