Which is equal to 2425 MHz?

To convert from megahertz (MHz) to gigahertz (GHz), you must divide the value by 1,000. The prefix 'mega' signifies one million, and 'giga' signifies one billion, so one GHz is exactly 1,000 times larger than one MHz. By dividing 2425 MHz by 1,000, or simply moving the decimal point three spaces to the left, you get 2.425 GHz. This frequency sits squarely in the 13-centimeter amateur radio band, widely used for Wi-Fi and high-frequency experimentation. The other options are incorrect because they represent moving the decimal point the wrong number of spaces, either converting it to a much larger or much smaller value than intended.
