How to Convert Terahertz to Hertz
1 terahertz = 1 × 1012 hertz
Hertz = Terahertz × 1 × 1012
Example: 1 THz × 1 × 1012 = 1 × 1012 Hz
Reverse Conversion
To convert hertz back to terahertz:
- Remember, 1 hertz equals 1 × 10-12 terahertz.
- To convert 1 × 1012 Hz to THz, multiply
1 × 1012 x 1 × 10-12, resulting in1 THz.

Definition of Terahertz
Terahertz: Far-Infrared and Research Frequency Unit
The terahertz (symbol: THz) is a unit of frequency equal to one trillion hertz (10¹² Hz). Terahertz radiation occupies the electromagnetic spectrum between microwave and infrared light, often called the "terahertz gap" because it was historically difficult to generate and detect. Recent advances have opened this band for security scanning, medical imaging, and 6G research.
Conversions to Other Units of Measurement:
- Hertz (Hz): 1 THz equals exactly 10¹² Hz (one trillion hertz).
- Gigahertz (GHz): 1 THz equals exactly 1,000 GHz. Future 6G wireless networks may operate in the 0.1-1 THz range.
- Megahertz (MHz): 1 THz equals 1,000,000 MHz.
Terahertz imaging can see through clothing, paper, and plastic without ionizing radiation, making it useful for airport security screening and non-destructive testing of materials.

Definition of Hertz
Hertz: The SI Unit of Frequency
The hertz (symbol: Hz) is the SI unit of frequency, defined as one cycle per second. It is named after Heinrich Rudolf Hertz, who first conclusively proved the existence of electromagnetic waves in 1887. One hertz means that an event repeats once per second.
Conversions to Other Units of Measurement:
- Kilohertz (kHz): 1 Hz equals 0.001 kHz. Kilohertz is commonly used for audio frequencies and AM radio broadcasting.
- Megahertz (MHz): 1 Hz equals 0.000001 MHz. Megahertz is used for FM radio and television broadcasting frequencies.
- Gigahertz (GHz): 1 Hz equals 10⁻⁹ GHz. Gigahertz is used for microwave frequencies, Wi-Fi, and modern processor clock speeds.
- Revolutions per Minute (rpm): 1 Hz equals 60 rpm. This conversion is fundamental in mechanical and electrical engineering for relating rotational speed to frequency.
- Radians per Second (rad/s): 1 Hz equals 2π rad/s (approximately 6.2832 rad/s). This angular frequency is essential in physics and signal processing.
The hertz is fundamental across science and engineering, from describing sound pitch and radio waves to processor clock speeds and power grid frequencies.

About the Terahertz
Terahertz radiation has unique properties: it can penetrate many non-metallic materials (clothing, paper, plastic, ceramics) but is absorbed by water and reflected by metals. This makes it ideal for security screening — airport body scanners use terahertz waves to detect concealed objects without ionizing radiation.
Research into 6G communications is exploring the 0.1-1 THz range, which could theoretically deliver data rates of 1 terabit per second — fast enough to download an entire 4K movie in less than a second.
About the Hertz
The hertz is named after Heinrich Hertz (1857-1894), who was the first to conclusively demonstrate the existence of electromagnetic waves predicted by James Clerk Maxwell's equations. Hertz's experiments in 1887 used a spark gap transmitter operating at about 50 MHz.
Power grids worldwide operate at either 50 Hz (Europe, Asia, Africa, most of South America) or 60 Hz (North America, parts of South America and Asia). This frequency determines the "hum" you sometimes hear from electrical equipment.
Frequently Asked Questions
How many hertz are in one terahertz?
One terahertz equals 1 × 1012 hertz. To convert, multiply the terahertz value by 1 × 1012. For the reverse, divide the hertz value by 1 × 1012 (or multiply by 1 × 10-12).
What is 10 terahertz in hertz?
10 terahertz = 1 × 1013 hertz. This is one of the most commonly searched conversions for this pair.
How precise is the terahertz-to-hertz conversion?
The factor 1 × 1012 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
