What Is a Frequency Converter?
A frequency converter transforms values between frequency units such as hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and RPM. It is used in electronics, telecommunications, audio engineering, and physics.
How to Use This Frequency Converter
- Enter the frequency value to convert.
- Select the source unit (e.g., MHz).
- Choose the target unit (e.g., GHz) and view the result.
Key Concepts
Frequency measures cycles per second. 1 Hz = 1 cycle/second. 1 kHz = 1,000 Hz. 1 MHz = 1,000,000 Hz. 1 GHz = 1,000,000,000 Hz. 1 RPM = 1/60 Hz. Audio frequencies range from 20 Hz to 20 kHz. Radio FM uses 88-108 MHz. Wi-Fi operates at 2.4 GHz and 5 GHz. Modern CPUs run at 3-5 GHz.
Result = Value × (From Factor ÷ To Factor)
Frequently Asked Questions
What frequency range can humans hear?
Human hearing spans roughly 20 Hz to 20,000 Hz (20 kHz). This range narrows with age, particularly the upper limit which can drop to 12-15 kHz in adults.
What is the relationship between frequency and wavelength?
Wavelength = speed / frequency. For electromagnetic waves: wavelength (m) = 299,792,458 / frequency (Hz). Higher frequencies have shorter wavelengths.
How do I convert RPM to Hz?
Divide RPM by 60 to get Hz. For example, 3000 RPM = 50 Hz. This is because Hz measures cycles per second and RPM measures revolutions per minute.
