What is a Frequency Converter?
A frequency converter is a tool that converts between units of frequency such as hertz, kilohertz, megahertz, gigahertz, and revolutions per minute. It is essential for electronics, telecommunications, audio engineering, and physics applications.
How to Convert Frequency Units
Select the frequency unit you want to convert from and the target unit using the dropdown menus. Enter your value in the input field and the converter instantly shows the equivalent frequency. Use this for radio frequencies, processor speeds, or audio frequencies.
Frequency Conversion Formulas
History of Frequency Measurement
The hertz is named after Heinrich Hertz, who proved the existence of electromagnetic waves in 1887. It was adopted as the SI unit of frequency in 1930, replacing "cycles per second." As technology advanced from radio to optical communications, practical units expanded from kHz to petahertz.
About This Frequency Converter
This frequency converter supports 16 units including hertz, kilohertz, megahertz, gigahertz, terahertz, petahertz, exahertz, millihertz, microhertz, revolution/second, revolution/minute, and cycle/second. It covers the full electromagnetic spectrum range.
Frequently Asked Questions
How do I convert MHz to GHz?
Divide the MHz value by 1000 to get GHz. For example, 2400 MHz ÷ 1000 = 2.4 GHz (common WiFi frequency).
How do I convert Hz to kHz?
Divide the hertz value by 1000 to get kilohertz. For example, 44100 Hz ÷ 1000 = 44.1 kHz (CD audio sample rate).
What is the difference between Hz and RPM?
Hertz measures cycles per second, while RPM measures revolutions per minute. 1 Hz = 60 RPM. A motor spinning at 3600 RPM operates at 60 Hz.
What frequency range is audible to humans?
Humans can typically hear frequencies between 20 Hz and 20,000 Hz (20 kHz). This range decreases with age, particularly at the high end.
What is terahertz radiation?
Terahertz (THz) radiation falls between microwave and infrared on the electromagnetic spectrum (0.1-10 THz). It is used in security scanning, medical imaging, and materials science.
