Frequently Asked Questions
How accurate is the frequency unit converter?
Our converter uses precise conversion factors based on international standards. Results are accurate to multiple decimal places, suitable for professional use in electronics, telecommunications, and scientific applications.
What is a hertz?
A hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It’s named after Heinrich Hertz, who proved the existence of electromagnetic waves.
What frequencies are used for WiFi?
WiFi typically operates at 2.4 GHz (2,400 MHz) and 5 GHz (5,000 MHz) frequencies. These are in the microwave portion of the electromagnetic spectrum.
How many hertz are in a kilohertz?
1 kilohertz equals exactly 1,000 hertz. This is a standard metric conversion.
What is the difference between hertz and megahertz?
A megahertz is one million times larger than a hertz. 1 MHz = 1,000,000 Hz. Megahertz is commonly used for radio frequencies and computer clock speeds.
What frequency range is used for FM radio?
FM radio broadcasts typically use frequencies between 88 and 108 megahertz (MHz) in most countries.
How do I convert gigahertz to megahertz?
To convert gigahertz to megahertz, multiply by 1,000. For example, 2.4 GHz equals 2,400 MHz.
What are terahertz used for?
Terahertz frequencies (10^12 Hz) are used in spectroscopy, imaging, and communications research. They occupy the region between microwave and infrared radiation.
