What is a Radians per Second and a Terahertz?

1 rad/s = 1 radian per second = 1/(2π) Hz ≈ 0.159155 Hz

Relationship to Hz:

  • ω (rad/s) = 2πf (Hz)
  • f (Hz) = ω/(2π) (rad/s)

Key relationship: 2π rad/s = 1 Hz (one complete cycle)

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 Radians 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.

Common Uses and Applications: rad/s vs terahertz

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

Common Uses for rad/s

Physics: Simple harmonic motion, pendulums, springs, wave equations. Electrical Engineering: AC circuit analysis, phasors, impedance. Mechanical Engineering: Rotational dynamics, angular velocity, vibration analysis. Control Systems: Transfer functions, frequency response, stability analysis.

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 Radians per Second (rad/s)

How do I convert rad/s to Hz?

Formula: Hz = rad/s ÷ (2π)

Examples:

  • 2π rad/s = 1 Hz
  • 6.28 rad/s ≈ 1 Hz
  • 377 rad/s = 60 Hz (US power frequency)
  • 314 rad/s = 50 Hz (European power frequency)

Reverse: rad/s = Hz × 2π

What is 2π rad/s?

2π rad/s = 1 Hz = 1 cycle per second

This is the key relationship:

  • One complete cycle = 2π radians = 360 degrees
  • So 2π rad/s = one full rotation per second
  • = 1 Hz
  • = 60 RPM

Example:

  • Object rotating at 2π rad/s completes exactly 1 full rotation every second

How do I convert rad/s to RPM?

Formula: RPM = rad/s × (60/2π) ≈ rad/s × 9.549

Examples:

  • 1 rad/s = 9.55 RPM
  • 10 rad/s = 95.5 RPM
  • 100 rad/s = 955 RPM

Reverse: rad/s = RPM × (2π/60) ≈ RPM × 0.1047

Derivation:

  • 1 revolution = 2π radians
  • 1 minute = 60 seconds
  • So: rad/s → rev/s → rev/min
  • rad/s × (1 rev / 2π rad) × (60 s / 1 min) = rad/s × 60/(2π) RPM

rad/s to RPM converter →

What is 377 rad/s?

377 rad/s = 60 Hz (US electrical power frequency)

Calculation: ω = 2πf = 2π × 60 ≈ 376.99 rad/s

This is the angular frequency of:

  • AC power in North America
  • 60 Hz electrical systems
  • Standard wall outlet frequency (in angular terms)

Used in electrical engineering for AC circuit calculations, phasor analysis, and impedance.

When should I use rad/s instead of Hz?

Use rad/s when:

  • Doing physics/engineering calculations
  • Working with differential equations
  • Analyzing AC circuits
  • Using transfer functions
  • Calculating angular displacement
  • Working with phasors

Use Hz when:

  • Describing oscillation rate to general audience
  • Specifying radio frequencies
  • Measuring audio frequencies
  • General frequency specifications
  • Non-technical contexts

Why rad/s in calculations?

  • Simplifies formulas: x = A sin(ωt) instead of x = A sin(2πft)
  • Direct angular displacement: θ = ωt
  • Natural for calculus: dx/dt, d²x/dt²

What's the difference between rad/s and degrees/s?

Conversion: 1 rad/s = 180/π deg/s ≈ 57.296 deg/s

Radians (rad/s):

  • Mathematical standard
  • Used in calculus and physics
  • 2π rad = one full rotation
  • Natural for trigonometric functions

Degrees (deg/s):

  • Intuitive for visualization
  • 360° = one full rotation
  • Common in navigation, astronomy
  • Easier for non-technical communication

Example:

  • 1 rad/s = 57.3 degrees per second
  • π rad/s = 180 degrees per second
  • 2π rad/s = 360 degrees per second = 1 revolution per second

For engineering and physics calculations, use rad/s.

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
