Frequently Asked Questions

About Terahertz and Gigahertz

Terahertz (THz)

The terahertz (THz) equals 10¹² Hz and occupies the electromagnetic spectrum between microwaves and infrared light. THz radiation was difficult to generate and detect until the 1990s, earning the region the nickname 'terahertz gap.'

Terahertz technology is emerging in security screening (airport body scanners can use THz), medical imaging, material characterization, and 6G wireless research. THz waves pass through clothing and packaging but are absorbed by water, making them useful for non-destructive testing.

Interesting fact: Many molecules have unique 'fingerprint' absorption spectra in the THz range, making THz spectroscopy a powerful tool for identifying substances — including explosives and pharmaceuticals — without contact or ionizing radiation.

Gigahertz (GHz)

The gigahertz (GHz) equals 1,000 MHz or 10⁹ Hz. It is the standard unit for modern processor clock speeds, Wi-Fi and 5G frequencies, and microwave communications. Consumer CPUs now operate at 3–6 GHz; 5G networks use bands from 600 MHz to 100 GHz.

GHz frequencies correspond to microwave wavelengths (centimeter to millimeter scale). Microwave ovens operate at 2.45 GHz; Wi-Fi uses 2.4 GHz and 5 GHz; mmWave 5G uses 24–100 GHz. Radar systems span 1–100 GHz depending on application.

Interesting fact: Water molecules resonate at around 22 GHz. Microwave ovens use 2.45 GHz — not the resonant frequency — because it penetrates food more deeply, heating it throughout rather than just at the surface.

About Terahertz to Gigahertz Conversion

Converting terahertz to gigahertz is essential across electronics, audio, radio communications, computing, and mechanical engineering. Frequency units span from sub-Hz seismic waves to THz optical signals — each discipline uses the scale most natural to its applications.

Quick reference: 10 THz = 1e+04 GHz and 1,000 THz = 1e+06 GHz. Reverse: 1 GHz = 0.001 THz. Exact factor: 1 THz = 1000 GHz.

All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
