Convert Gigahertz (GHz) to Terahertz (THz)
1 gigahertz equals 0.001 terahertz.
Gigahertz to Terahertz Converter
How to Convert Gigahertz to Terahertz
1 gigahertz = 0.001 terahertz
Terahertz = Gigahertz × 0.001
Example: 1 GHz × 0.001 = 0.001 THz
Reverse Conversion
To convert terahertz back to gigahertz:
- Remember, 1 terahertz equals 1000 gigahertz.
- To convert 0.001 THz to GHz, multiply
0.001 x 1000, resulting in1 GHz.

Definition of Gigahertz
Gigahertz: Microwave and Computing Frequency Unit
The gigahertz (symbol: GHz) is a unit of frequency equal to one billion hertz (10⁹ Hz). It is the standard unit for describing modern processor clock speeds, Wi-Fi frequencies, and microwave communications. The 2.4 GHz and 5 GHz bands are familiar to anyone who has configured a Wi-Fi router.
Conversions to Other Units of Measurement:
- Hertz (Hz): 1 GHz equals exactly 1,000,000,000 Hz. A 3 GHz processor executes 3 billion clock cycles per second.
- Megahertz (MHz): 1 GHz equals exactly 1,000 MHz. This conversion is frequently used when comparing old and new processor specifications.
- Kilohertz (kHz): 1 GHz equals 1,000,000 kHz.
- Terahertz (THz): 1 GHz equals 0.001 THz. The terahertz gap between microwave and infrared is an active area of research.
Modern smartphones typically have processors clocked between 2-3 GHz, while desktop CPUs can boost above 5 GHz. The unit is also essential in radar, satellite communications, and 5G cellular networks.

- SI decimal multiple of hertz; 1 GHz = 1,000,000,000 Hz = 10⁹ Hz
- Common equivalents
- 1 GHz = 10⁹ Hz (exact)
- 1 GHz = 1,000 MHz (exact)
- 1 GHz = 0.001 THz (exact)

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.

About the Gigahertz
Modern CPU clock speeds hover around 3-5 GHz because increasing frequency further creates excessive heat. Instead, processors add more cores to increase performance. The highest verified CPU overclock reached 9.008 GHz on an AMD FX-8370 in 2024.
5G cellular networks use multiple frequency bands, including sub-6 GHz bands (similar to 4G) and millimeter wave (mmWave) bands from 24-100 GHz, which offer extremely high speeds but limited range.
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.
Frequently Asked Questions
How many terahertz are in one gigahertz?
One gigahertz equals 0.001 terahertz. To convert, multiply the gigahertz value by 0.001. For the reverse, divide the terahertz value by 0.001 (or multiply by 1000).
What is 100 gigahertz in terahertz?
100 gigahertz = 0.1 terahertz. This is one of the most commonly searched conversions for this pair.
Is the gigahertz-to-terahertz conversion exact?
Yes. The factor 0.001 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
