Frequently Asked Questions
About Hertz and Terahertz
Hertz (Hz)
The hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It was named after Heinrich Rudolf Hertz, the German physicist who first conclusively proved the existence of electromagnetic waves in 1887–1888. The unit was adopted by the General Conference on Weights and Measures in 1960.
Hertz describes the frequency of everything from sound waves (human hearing: 20–20,000 Hz) to AC power (50 or 60 Hz) to radio waves and processor clocks. A standard A4 musical note vibrates at exactly 440 Hz.
Interesting fact: Heinrich Hertz reportedly said his discovery of radio waves would have no practical use. Within a decade, Marconi used them to transmit the first transatlantic radio signal. Hertz died at 36, never knowing the technology named after him would transform civilization.
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.
About Hertz to Terahertz Conversion
Converting hertz to terahertz 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 Hz = 1.0000e-11 THz and 1,000 Hz = 1.0000e-9 THz. Reverse: 1 THz = 1.0000e12 Hz. Exact factor: 1 Hz = 1.0000e-12 THz.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
