Megahertz Conversion

Megahertz (MHz) is a common unit of frequency that represents one million cycles per second and is particularly known for its vital role in telecommunications and computing. The term hertz pays homage to Heinrich Hertz, the first person to conclusively prove the existence of electromagnetic waves. In radio broadcasting, the station dial numbers you tune into represent megahertz, which indicate the carrier frequency of the radio station. For example, a frequency of 101.1 MHz means the wave completes 101.1 million cycles every second!

In computing, the speed of the early personal computers was often measured in megahertz. Though we’ve progressed to gigahertz in modern-day processors, the megahertz era marked some groundbreaking advancements in technology. The original IBM PC, introduced in 1981, had a processor speed of just 4.77 MHz. Today, such performance pales in comparison, revealing the incredible strides in processing power over the decades.
