About the units
Gigahertz (GHz)
Wi-Fi operates around 2.4, 5 and 6 GHz. One gigahertz equals 1,000,000,000 hertz (Hz).
Centimeter (cm)
The centimeter (cm) is a unit of frequency to wavelength in the International System of Units (SI). It is inversely related to hertz: Hz = 29,979,245,800 ÷ value.
Frequently asked questions
What is the formula to convert gigahertz to centimeters?
cm = 29.9792458 ÷ GHz. Gigahertz and centimeters are inversely related: when one goes up the other goes down. Divide 29.9792458 by the value — do not multiply.
What is 5 gigahertz in centimeters?
5 GHz = 5.99584916 cm.
Why is this not a simple multiplication?
One unit measures the quantity directly and the other measures its inverse, so a larger value in one means a smaller value in the other. That is why the formula divides a constant by your value.
Is this GHz to cm converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
