Frequency Converter – Convert Hz, kHz, MHz, GHz, RPM

Easily convert frequencies between Hertz (Hz), Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz), and Revolutions per Minute (RPM) with our free online Frequency Converter. No math or formulas required – just enter a value and get instant results!

What is Frequency?

Frequency is how often something happens per unit of time. For example, the frequency of a sound wave tells us how many times it vibrates per second. It is measured in Hertz (Hz), where 1 Hz = 1 cycle per second. Higher frequencies are measured in kHz, MHz, or GHz depending on the application.

Why Use a Frequency Converter?

A frequency converter is useful for:

• Electronics and radio engineering to switch between Hz, kHz, and MHz.
• Mechanical engineering to convert RPM to Hz for rotating machinery.
• Science experiments where accurate frequency measurements are required.
• Everyday applications like understanding AC electrical frequency or sound waves.

How to Use the Frequency Converter

Follow these simple steps:

1. Enter the frequency value in the input box.
2. Select the unit you are converting from (Hz, kHz, MHz, GHz, or RPM).
3. Click the Convert button.
4. See the results instantly in all units.
5. Use the Reset button to clear and enter a new value.

Common Frequency Units Explained

• Hertz (Hz) – The basic unit of frequency. 1 Hz = 1 cycle per second.
• Kilohertz (kHz) – 1 kHz = 1,000 Hz. Used for audio signals and radio waves.
• Megahertz (MHz) – 1 MHz = 1,000,000 Hz. Used for radio broadcasting, computers, and Wi-Fi.
• Gigahertz (GHz) – 1 GHz = 1,000,000,000 Hz. Used for microwave, satellite, and CPU clock speeds.
• Revolutions per Minute (RPM) – Measures rotations per minute. 1 RPM = 1/60 Hz.

Examples of Frequency Conversion

- 60 Hz AC electricity = 60 cycles per second.
- 1,000 Hz = 1 kHz.
- 2.4 GHz Wi-Fi = 2,400,000 kHz.
- A motor running at 3,000 RPM = 50 Hz.

Tips for Accurate Conversion

• Always check the units before converting.
• Use this online tool to avoid manual calculation errors.
• Remember that 1 RPM is smaller than 1 Hz (divide by 60 to get Hz).
• Large units like GHz will appear smaller in numbers than Hz or kHz.

FAQs – Frequency Converter

1. What is the easiest way to convert frequencies?

The easiest way is to use our online frequency converter. Enter the value, select units, and get results instantly.

2. How many Hz are in 1 kHz?

1 kHz = 1,000 Hz.

3. How do I convert RPM to Hz?

Divide the RPM value by 60. For example, 120 RPM = 2 Hz.

4. What is the difference between MHz and GHz?

MHz (Megahertz) = 1,000,000 Hz. GHz (Gigahertz) = 1,000,000,000 Hz. GHz is 1,000 times higher than MHz.

5. Who uses a frequency converter?

Engineers, scientists, electronics hobbyists, mechanics, and students use frequency converters for accurate measurements and calculations.
