Frequency Converter

What is Frequency?

Frequency is the number of cycles (repetitions) of a wave per second.

It tells us how often an event repeats over time.

The SI unit of frequency is hertz (Hz), which equals 1 cycle per second.

 

 Why Use a Frequency Converter?

• Quickly switch between hertz, kilohertz, megahertz, and gigahertz.
• Essential for radio, telecommunications, and electronics.
• Saves time when working with different measurement systems.

 

 Common Applications

• Music & Sound – Measuring pitch (audio frequency).
• Radio & TV Broadcasting – Signal frequencies.
• Telecommunications – WiFi, 4G, 5G frequency ranges.
• Physics & Engineering – Vibrations, resonance, and oscillations.
• Medical Devices – Ultrasound frequency conversions.

 

 How to Use the Frequency Converter

1. Enter the value in your chosen unit (e.g., MHz).

2. Select your starting unit.

3. Instantly view results in all supported frequency units.

 

 Supported Units

• Hertz (Hz) – cycles per second
• Kilohertz (kHz) – 1,000 Hz
• Megahertz (MHz) – 1,000,000 Hz
• Gigahertz (GHz) – 1,000,000,000 Hz
• Terahertz (THz) – 1 trillion Hz
• Revolutions per Minute (RPM) – mechanical frequency
• Degrees per Second (°/s) – angular frequency
• Radians per Second (rad/s)

 

 Example Conversions

• 1 kHz = 1,000 Hz
• 1 MHz = 1,000,000 Hz
• 1 GHz = 1,000,000,000 Hz
• 1 Hz = 60 RPM
• 1 rad/s ≈ 0.159 Hz

 

Who Uses This Tool?

• Students & Teachers – Physics & math frequency problems.
