Frequency Converter

Our Frequency Converter is a versatile tool that helps you convert between different units of frequency: hertz (Hz), kilohertz (kHz), megahertz (MHz), and gigahertz (GHz). Whether you’re working with audio signals, radio frequencies, processor speeds, or any other frequency-based measurements, this calculator makes frequency conversion simple and accurate.

Understanding Frequency Units

Base Unit

Hertz (Hz)

The hertz is the SI unit of frequency, defined as one cycle per second. It measures how many times an event occurs in one second, such as the oscillations of a wave or the clock cycles of a processor.

Metric Prefixes

Kilohertz (kHz)

1 kHz = 1,000 Hz. Commonly used in audio frequencies and low-frequency radio signals.

Megahertz (MHz)

1 MHz = 1,000,000 Hz = 1,000 kHz. Used for radio frequencies and computer clock speeds.

Gigahertz (GHz)

1 GHz = 1,000,000,000 Hz = 1,000,000 kHz = 1,000 MHz. Common in modern processor speeds and high-frequency communications.

Conversion Formulas

Here are the formulas used for converting between different frequency units:

Base Unit (Hertz) Conversions

• 1 kilohertz = 1,000 hertz
• 1 megahertz = 1,000,000 hertz
• 1 gigahertz = 1,000,000,000 hertz

Other Common Conversions

• 1 megahertz = 1,000 kilohertz
• 1 gigahertz = 1,000 megahertz

Common Frequency References

Here are some common frequency measurements for reference:

• Human hearing range: 20 Hz - 20 kHz
• Standard AC power: 50/60 Hz
• AM radio: 535 - 1,605 kHz
• FM radio: 88 - 108 MHz
• Wi-Fi networks: 2.4 GHz, 5 GHz
• CPU clock speeds: 2 - 5 GHz
• Mobile networks:
  • 4G LTE: 600 MHz - 2.5 GHz
  • 5G: 24 - 47 GHz

How to Use the Calculator

Applications

Frequency conversion is essential in many fields:

• Electronics: Signal processing and circuit design
• Telecommunications: Radio and wireless communications
• Computing: Processor and memory speeds
• Audio Engineering: Sound frequency analysis
• RF Engineering: Radio frequency applications
• Medical Equipment: Ultrasound and imaging devices

Tips for Accurate Conversion

• Always use decimal points for precise measurements
• Double-check critical measurements
• Consider rounding to appropriate precision for your application
• Keep in mind the context of your frequency needs
• Be aware of bandwidth and frequency range requirements

Technical Notes

This calculator provides conversions accurate to two decimal places, which is sufficient for most practical purposes. For extremely precise measurements or scientific applications, please use specialized measuring equipment and conversion methods.

Common Conversion Scenarios

• Converting radio frequencies between bands
• Analyzing audio frequency ranges
• Specifying computer component speeds
• Working with wireless communication frequencies
• Converting between different measurement standards
• Calculating signal periods and wavelengths

Frequency and Period

The period (T) of a wave is the reciprocal of its frequency (f):

$T = \frac{1}{f}$

For example:

• 1 Hz = 1 second period
• 1 kHz = 1 millisecond period
• 1 MHz = 1 microsecond period
• 1 GHz = 1 nanosecond period

This relationship is useful when working with timing in electronic circuits and signal processing applications.
