What is frequency (Hz, kHz, MHz, GHz, THz)?

Frequency measures how often something repeats per second. The base unit is Hertz (Hz), where 1 Hz means one complete cycle per second. It's used to describe oscillations, waves, and periodic events across electronics, radio signals, processors, and communication systems.

Larger units are just scaled versions of Hertz:

  • 1 kHz (kilohertz) = 1,000 Hz
  • 1 MHz (megahertz) = 1,000,000 Hz
  • 1 GHz (gigahertz) = 1,000,000,000 Hz
  • 1 THz (terahertz) = 1,000,000,000,000 Hz

Each step up multiplies by 1,000, making it easy to handle both very small and very large frequencies.

How to convert frequency units

Hz to kHz, MHz, GHz and THz (÷ 1,000)

To convert to a larger unit, divide by 1,000:

Larger Unit = Hz ÷ 1,000

Example: 5,000,000 Hz = 5,000,000 ÷ 1,000,000 = 5 MHz

kHz, MHz, GHz and THz to Hz (× 1,000)

To convert to a smaller unit, multiply by 1,000:

Hz = Larger Unit × 1,000

Example: 2.5 GHz = 2.5 × 1,000,000,000 = 2,500,000,000 Hz

Frequency Scale Explained

1 Hz = 10⁰ = 1
1 kHz = 10³ = 1,000
1 MHz = 10⁶ = 1,000,000
1 GHz = 10⁹ = 1,000,000,000
1 THz = 10¹² = 1,000,000,000,000

Each unit is 10³ times larger than the previous one.

Real-world examples

WiFi Frequency

Given:
2.4 GHz WiFi signal
2.4 × 1,000,000,000 = 2,400,000,000 Hz

CPU Clock Speed

Given:
3.5 GHz processor
3.5 × 1,000,000,000 = 3,500,000,000 Hz

Frequently Asked Questions

What is 1 MHz in Hz?

1 MHz equals 1,000,000 Hz. Since MHz stands for megahertz, the 'mega' prefix means one million.

How many Hz are in 1 GHz?

1 GHz equals 1,000,000,000 Hz. The 'giga' prefix means one billion, so GHz is for very high frequencies.

Is MHz bigger than kHz?

Yes. 1 MHz is exactly 1,000 times larger than 1 kHz because each step up multiplies by 1,000.

What is frequency used for?

Frequency describes oscillations in radio signals, wireless networks, audio waves, CPUs, and any periodic phenomena.

How do I convert GHz to MHz?

Multiply by 1,000. For example: 2 GHz × 1,000 = 2,000 MHz

What is 2.4 GHz in Hz?

2.4 GHz = 2.4 × 1,000,000,000 = 2,400,000,000 Hz (common WiFi frequency)

What does Hz actually measure?

Hertz measures cycles per second. 1 Hz means the event repeats once every second.

Is higher frequency always better?

Not always. Higher frequency means faster but shorter range. It depends on the application's requirements.
