What is Frequency Conversion?

Frequency conversion is the process of converting measurements of oscillatory motion or wave frequency from one unit to another. Our frequency converter tool supports both scientific frequency units and rotational speed measurements.

Common units include hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and revolutions per minute (RPM). These conversions are essential for electronics, telecommunications, audio engineering, and mechanical systems.

Simply enter your value in the "From" field, select the original unit, choose your target unit in the "To" field, and the converter will instantly display the converted result along with the conversion formula.

Frequency Conversion Examples

Audio Example

Audio frequency ranges:

  • 440 Hz = 0.44 kHz (A4 note)
  • 1000 Hz = 1 kHz
  • 20 kHz = 20,000 Hz

Electronics Example

Processor and signal frequencies:

  • 2.4 GHz = 2400 MHz
  • 100 MHz = 0.1 GHz
  • 1 GHz = 1000 MHz

Mechanical Example

Rotational speed conversions:

  • 60 RPM = 1 Hz
  • 3600 RPM = 60 Hz
  • 1200 RPM = 20 Hz

Frequently Asked Questions

How many hertz in a megahertz?

One megahertz (MHz) equals exactly 1,000,000 hertz (Hz). This metric prefix conversion is commonly used in radio, telecommunications, and computing.

How do I convert RPM to Hz?

To convert revolutions per minute to hertz, divide by 60. For example, 120 RPM ÷ 60 = 2 Hz. This converts rotational speed to cycles per second.

How many GHz in a terahertz?

One terahertz (THz) equals 1000 gigahertz (GHz). This unit is used for extremely high-frequency applications like infrared spectroscopy and future computing.

What is the formula for kHz to MHz conversion?

To convert kilohertz to megahertz, divide by 1000. For example, 5000 kHz ÷ 1000 = 5 MHz. This is commonly used in radio frequency applications.

How many Hz in a RPM?

To convert RPM to Hz, divide by 60. One revolution per minute equals approximately 0.01667 Hz. This conversion is essential for motor speed calculations.
