Frequently Asked Questions

About Kilohertz and Terahertz

Kilohertz (kHz)

The kilohertz (kHz) equals 1,000 Hz and is the standard frequency unit for AM radio, audio signals, and early computing. The AM radio band spans 530–1,700 kHz; human speech occupies roughly 100–8,000 Hz, and telephone systems originally targeted 300–3,400 Hz.

Kilohertz frequencies are used in ultrasound cleaning (20–40 kHz), sonar (1–500 kHz), AM broadcasting (530–1,710 kHz), and audio sampling rates (44.1 kHz for CD audio). Early microprocessors operated in the low MHz range, making kHz relevant to 1970s computing history.

Interesting fact: The 44.1 kHz audio sampling rate (CD standard) was chosen partly because it fit within the bandwidth of a modified video recorder — the original storage medium for digital audio masters in the late 1970s.

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 Kilohertz to Terahertz Conversion

Converting kilohertz 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 kHz = 1.0000e-8 THz and 1,000 kHz = 1.0000e-6 THz. Reverse: 1 THz = 1e+09 kHz. Exact factor: 1 kHz = 1.0000e-9 THz.

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