Common values, ready to copy:

hertz	terahertz
1 Hz	1.0000e-12 THz
2 Hz	2.0000e-12 THz
5 Hz	5.0000e-12 THz
10 Hz	1.0000e-11 THz
25 Hz	2.5000e-11 THz
50 Hz	5.0000e-11 THz
100 Hz	1.0000e-10 THz
1,000 Hz	1.0000e-9 THz

Formula

terahertz = hertz × 1e-12

Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.

About Hertz and Terahertz

Hertz (Hz): Cycles per second; named for Heinrich Hertz, who experimentally demonstrated electromagnetic waves in 1887. Common uses: Audio (Hz range for human hearing is 20-20,000 Hz), AC power frequency (50 or 60 Hz), and the SI base unit for any periodic phenomenon.

Terahertz (THz): A trillion hertz; the unit for far-infrared light and emerging high-bandwidth applications. Common uses: Far-infrared imaging, some emerging 6G research, and the frequency range just below visible light.

How the conversion works

Frequency uses the SI hertz (Hz, cycles per second). 1 kHz = 1,000 Hz; 1 MHz = 1 million Hz; 1 GHz = 1 billion Hz. RPM and BPM are both "cycles per minute": 60 RPM = 1 Hz.

The exact relationship is terahertz = hertz × 1e-12, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.

When this conversion matters

Converting between hertz and terahertz comes up wherever frequency measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
