1 THz = 1,000,000,000,000 Hz = 1,000 GHz = 1,000,000 MHz
Wavelength: 1 THz ≈ 300 micrometers (0.3 mm)
1 cps = 1 Hz = 1 cycle per second = 1 complete oscillation per second
Note: The Terahertz is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Cycles per Second belongs to the imperial/US customary system.
History of the Terahertz and Cycles per Second
Before 1960: "Cycles per second" was the standard term
- Common abbreviations: c/s, c.p.s., cps, ~/s
1960: Renamed to "hertz" (Hz)
- Honors Heinrich Hertz (1857-1894)
- Adopted at 11th CGPM (General Conference on Weights and Measures)
- Simplified terminology and standardized notation
Why the change?
- Shorter, more convenient
- Honors a pioneering physicist
- Consistent with other SI units named after scientists (ampere, watt, volt, etc.)
- International standardization
Common Uses and Applications: terahertz vs cps
Explore the typical applications for both Terahertz (imperial/US) and Cycles per Second (imperial/US) to understand their common contexts.
Common Uses for terahertz
Security Imaging: Airport body scanners, contraband detection (THz waves penetrate clothing but not metal/water). Medical Imaging: Non-ionizing tissue imaging, cancer detection, dental imaging. Spectroscopy: Material identification, chemical analysis, pharmaceutical quality control. 6G Research: Future wireless communications (sub-THz bands 100-300 GHz). Astronomy: Studying cold molecular clouds, star formation regions.
When to Use cps
(Historical & Current)
Historical Technical Documents: Pre-1960 radio, electronics, and acoustics literature - understanding older specs. Some Fields Still Use "cycles": Audio engineering may say "cycles" colloquially. Education: Teaching frequency concepts before introducing Hz notation. Older Equipment: Vintage test equipment labeled in cps. Legacy Systems: Industrial control systems that predate 1960 standardization.
Additional Unit Information
About Terahertz (THz)
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
