How many gigahertz are in 20,000 megahertz?

To convert megahertz to gigahertz, you need to understand the relationship between the two units. One gigahertz is equal to 1,000 megahertz. Therefore, to convert megahertz to gigahertz, you divide the number of megahertz by 1,000.

In this case, you start with 20,000 megahertz. When you perform the conversion:

20,000 megahertz ÷ 1,000 = 20 gigahertz.

This means that 20,000 megahertz is equal to 20 gigahertz, making that the correct answer. Understanding this conversion process is essential for working with frequencies in telecommunications and networking, as it helps interpret specifications and standards properly.
