About the units
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.
Gigahertz (GHz)
Wi-Fi operates around 2.4, 5 and 6 GHz. One gigahertz equals 1,000,000,000 hertz (Hz).
Frequently asked questions
What is the formula to convert centimeters to gigahertz?
GHz = 29.9792458 ÷ cm. Centimeters and gigahertz are inversely related: when one goes up the other goes down. Divide 29.9792458 by the value — do not multiply.
What is 400 centimeters in gigahertz?
400 cm = 0.0749481145 GHz.
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 cm to GHz 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.
