Megahertz (MHz) and gigahertz (GHz) are units used to measure frequency, with 1 GHz equating to 1,000 MHz. To convert megahertz to gigahertz, divide the number of megahertz by 1,000. For example, 2,500 MHz divided by 1,000 equals 2.5 GHz. Conversely, to convert gigahertz to megahertz, multiply the number of gigahertz by 1,000; thus, 3.2 GHz multiplied by 1,000 equals 3,200 MHz. This conversion is essential in fields like telecommunications and computing, where frequencies often range from MHz to GHz. For instance, many Wi-Fi networks operate at frequencies of 2.4 GHz or 5 GHz, which correspond to 2,400 MHz and 5,000 MHz, respectively.
