Local Processing

Convert between frequency units including hertz, kilohertz, megahertz, gigahertz, and terahertz.

How It Works & Processing Standards

Convert between the units listed below using Hz as the base unit.

kHz1 kHz = 1000 Hz
MHz1 MHz = 1000000 Hz
GHz1 GHz = 1000000000 Hz
THz1 THz = 1000000000000 Hz

Tool processing runs in your browser. If you create a calculator or conversion share link, its values are included in the URL. See the privacy policy for account, analytics and advertising data.

Puts audio (Hz, kHz), radio (MHz) and Wi-Fi or CPU (GHz) frequencies on the same scale.

How to Use Frequency Converter

  1. 1
    Enter a valueDecimals and negative numbers (for temperature, say) are accepted.
  2. 2
    Choose unitsPick the unit you have and the unit you want. The swap button reverses the direction.
  3. 3
    Read, copy or shareResults show up to six decimal places. Copy them or create a share link with the same value.

Examples

2.4 GHz Wi-Fi in MHz
Input: 2.4 GHz → MHz
Result: 2400
A4 at 440 Hz in kHz
Input: 440 Hz → kHz
Result: 0.44

Common Use Cases

  • Wireless channel frequencies in MHz
  • Comparing audio sample rates such as 44.1 kHz
  • Matching circuit clock frequencies

Frequently Asked Questions (FAQ)

Can I get the period in seconds?

The period is 1 ÷ frequency; 440 Hz is about 0.00227 s. This tool converts between frequency units only.

What about rpm?

1 Hz = 60 rpm. rpm is not included here.
