If a frequency readout shows a reading of 2425 MHz, what is that frequency in GHz?

  1. 0.2425 GHz

  2. 2.425 GHz

  3. 24.25 GHz

  4. 242.5 GHz

The correct answer is: 2.425 GHz

To convert a frequency measured in megahertz (MHz) to gigahertz (GHz), you divide the value by 1,000 because 1 GHz is equal to 1,000 MHz. In this case, the frequency is 2425 MHz. To convert this to GHz, the calculation would be: 2425 MHz ÷ 1000 = 2.425 GHz. Thus, the frequency of 2425 MHz is equal to 2.425 GHz. This demonstrates the proper method of converting from one frequency unit to another, reinforcing the understanding of how different frequency units relate to each other in the electromagnetic spectrum.
