Gigahertz to Terahertz Converter

How do I convert THz to GHz?

Formula: GHz = THz × 1,000

Examples:

• 1 THz = 1,000 GHz
• 0.3 THz = 300 GHz (6G research)
• 10 THz = 10,000 GHz

What is terahertz radiation?

Terahertz radiation is electromagnetic waves between microwaves and infrared:

Frequency range: 0.1-10 THz (typically) Wavelength: 3 mm - 30 micrometers

Properties:

• Non-ionizing (safe, unlike X-rays)
• Penetrates paper, clothing, plastics, ceramics
• Blocked by water and metals
• Can image internal structures

Applications: Security screening, medical imaging, quality control.

Is terahertz radiation dangerous?

Generally safe - terahertz radiation is non-ionizing:

Safety:

• Lower energy than visible light
• Cannot damage DNA like X-rays
• Does not cause cancer
• May cause slight heating at very high power

Current exposure limits: Power density limits for occupational exposure around 10 W/m² (varies by country).

Much safer than X-rays for imaging applications.

What is the terahertz gap?

The terahertz gap refers to the frequency range (0.1-10 THz) that was historically difficult to generate and detect:

• Too fast for electronic devices (transistors)
• Too slow for optical devices (lasers)

Modern solutions:

• Quantum cascade lasers
• Photoconductive antennas
• Frequency multipliers
• Synchrotron sources

This gap has largely been closed with 21st-century technology.

How do I convert THz to Hz?

Formula: Hz = THz × 1,000,000,000,000

Examples:

• 1 THz = 1,000,000,000,000 Hz (1 trillion Hz)
• 0.5 THz = 500,000,000,000 Hz
• 10 THz = 10,000,000,000,000 Hz
