Gigahertz to Terahertz: The Essentials
About the Gigahertz
Gigahertz (GHz) is a unit of frequency measurement. 1 gigahertz is equal to 0.0010000 terahertz.
About the Terahertz
Terahertz (THz) is a unit of frequency measurement. 1 terahertz is equal to 1000.0000000 gigahertz.
Frequency Conversion Applications
Frequency units span from hertz (cycles per second) through kilohertz (AM radio), megahertz (FM radio, processors), to gigahertz (Wi-Fi, 5G, microprocessors) and terahertz (scientific imaging). RPM to hertz conversion connects mechanical rotation to electrical frequency in generators and motors. Musicians convert between frequency (Hz) and musical pitch.

How to Convert GHZ to THZ (Gigahertz to Terahertz)?
We can convert gigahertz to terahertz by using an example.
Example:
Convert 20 Gigahertz to Terahertz?
We know 1 Gigahertz = 0.0010000 terahertz; 1 Terahertz = 1000.0000000 gigahertz.
20 gigahertz = ___THz
20 × 0.0010000 = 0.02000 THz (we know 1 gigahertz = 0.0010000 terahertz)
Answer:
20 gigahertz = 0.02000 terahertz
Gigahertz to Terahertz: Entering the THz Gap
Terahertz (THz) frequencies lie between microwave and infrared light, spanning roughly 0.1 to 10 THz. Converting GHz to THz means dividing by 1,000 since 1 THz = 1,000 GHz. This range is increasingly important for 6G research, security imaging, and spectroscopy applications.
- Start with the frequency in GHz.
- Divide by 1,000.
- The result is the frequency in THz.
- Example: 300 GHz ÷ 1,000 = 0.3 THz.
GHz to THz: The Terahertz Spectrum
Frequencies at the boundary between electronics and photonics:
| Gigahertz | Terahertz |
|---|---|
| 100 GHz | 0.1 THz |
| 140 GHz | 0.14 THz |
| 300 GHz | 0.3 THz |
| 500 GHz | 0.5 THz |
| 1,000 GHz | 1 THz |
| 3,000 GHz | 3 THz |
| 10,000 GHz | 10 THz |
| 30,000 GHz | 30 THz |
Examples: GHz to THz in Research
Question 1: A 6G prototype operates at 140 GHz. Express in THz.
Solution:
THz = GHz ÷ 1,000
= 140 ÷ 1,000
= 0.14 THz
Answer: 140 GHz = 0.14 THz — a candidate frequency for future 6G mobile networks.
Question 2: A security scanner uses 250 GHz radiation. Convert to THz.
Solution:
THz = GHz ÷ 1,000
= 250 ÷ 1,000
= 0.25 THz
Answer: 250 GHz = 0.25 THz — penetrates clothing but not skin, used in airport body scanners.
Question 3: A spectroscopy laser operates at 2,520 GHz. What is this in THz?
Solution:
THz = GHz ÷ 1,000
= 2,520 ÷ 1,000
= 2.52 THz
Answer: 2,520 GHz = 2.52 THz — used for molecular fingerprint identification.

The Terahertz Gap: Why This Band Is Special
The "terahertz gap" (roughly 100 GHz to 10 THz / 0.1-10 THz) has historically been difficult to access because it falls between electronic oscillators (which work well below 100 GHz) and optical/laser sources (which work above 10 THz). Recent advances in quantum cascade lasers and photomixing are closing this gap, enabling applications in medical imaging, materials science, and ultra-high-speed wireless.
6G and Beyond: Terahertz Communications
While 5G mmWave uses 24-39 GHz (0.024-0.039 THz), research for 6G targets 100-300 GHz (0.1-0.3 THz) frequencies. These bands offer enormous bandwidth (potentially 100+ Gbps per link) but face severe atmospheric absorption and very short range. Indoor THz links, device-to-device communication, and backhaul applications are the most promising near-term use cases for frequencies above 100 GHz.
Key Takeaways
- 1 GHz = 0.001 THz (divide by 1,000).
- The terahertz range spans 100 GHz (0.1 THz) to 10,000 GHz (10 THz).
- 6G research targets 100-300 GHz (0.1-0.3 THz) for ultra-fast wireless.
- THz radiation penetrates many materials but is blocked by water and metal.
- Move the decimal three places left to convert GHz to THz.
