What is a Terahertz and a Megahertz?

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

Wavelength: 1 THz ≈ 300 micrometers (0.3 mm)

1 MHz = 1,000,000 Hz = 1,000 kHz = 0.001 GHz

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

Common Uses and Applications: terahertz vs megahertz

Explore the typical applications for both Terahertz (imperial/US) and Megahertz (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 megahertz

FM Radio: 88-108 MHz broadcasting band (FM stereo). Computer RAM: DDR4 2400-3200 MHz, DDR5 4800-6400 MHz memory frequencies. WiFi/Bluetooth: 2.4 GHz (2400 MHz), 5 GHz (5000 MHz) wireless bands. TV Broadcasting: VHF television 54-216 MHz, UHF 470-890 MHz.

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

About Megahertz (MHz)

How do I convert MHz to GHz?

Formula: GHz = MHz ÷ 1,000

Examples:

  • 1,000 MHz = 1 GHz
  • 2,400 MHz = 2.4 GHz (WiFi)
  • 3,500 MHz = 3.5 GHz (CPU)
  • 5,000 MHz = 5 GHz (WiFi 5 GHz band)

MHz to GHz converter →

What is 2400 MHz?

2400 MHz = 2.4 GHz is a common wireless frequency band.

Uses:

  • WiFi (802.11b/g/n/ax): 2.4 GHz band (2400-2483.5 MHz)
  • Bluetooth: 2400-2483.5 MHz
  • Microwave ovens: 2450 MHz (can interfere with WiFi)
  • Cordless phones: Many use 2.4 GHz
  • Zigbee/IoT devices: Often 2.4 GHz

Pros: Good range, better wall penetration Cons: Crowded band, more interference

How do I convert MHz to Hz?

Formula: Hz = MHz × 1,000,000

Examples:

  • 1 MHz = 1,000,000 Hz
  • 100 MHz = 100,000,000 Hz
  • 2.4 MHz = 2,400,000 Hz
  • 0.5 MHz = 500,000 Hz = 500 kHz

What is FM radio frequency range?

FM Radio Band: 88-108 MHz (in most countries)

Variations by region:

  • USA/Canada: 88.1-107.9 MHz (non-commercial starts at 88.1)
  • Europe: 87.5-108 MHz
  • Japan: 76-95 MHz (different band entirely)
  • Eastern Europe/Russia: 65.8-74 MHz (also 88-108)

Channel spacing:

  • USA: 200 kHz (0.2 MHz) - channels 0.2 MHz apart
  • Europe: 100 kHz (0.1 MHz) - twice as many stations possible

Why FM?:

  • Better sound quality than AM
  • Less interference
  • Stereo capable
  • "FM" = Frequency Modulation (varies frequency to encode audio)

How do I convert MHz to kHz?

Formula: kHz = MHz × 1,000

Examples:

  • 1 MHz = 1,000 kHz
  • 0.5 MHz = 500 kHz
  • 100 MHz = 100,000 kHz
  • 2.4 MHz = 2,400 kHz
