What is a Cycles per Second and a Terahertz?

1 cps = 1 Hz = 1 cycle per second = 1 complete oscillation per second

1 THz = 1,000,000,000,000 Hz = 1,000 GHz = 1,000,000 MHz

Wavelength: 1 THz ≈ 300 micrometers (0.3 mm)

Note: The Cycles per Second is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Terahertz belongs to the imperial/US customary system.

History of the Cycles per Second and Terahertz

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: cps vs terahertz

Explore the typical applications for both Cycles per Second (imperial/US) and Terahertz (imperial/US) to understand their common contexts.

Common Uses for 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.

When to Use 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.

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
