Megahertz is a term used to describe the frequency of electromagnetic waves, including radio waves and microwaves. Some synonyms for megahertz include MHz, megacycles per second (Mc/s), and million cycles per second (MCPs). These terms can be used interchangeably to talk about the frequency at which signals are transmitted wirelessly. Other related terms include gigahertz (GHz), which is equivalent to 1,000 megahertz, and kilohertz (kHz), which is 1,000 times smaller than a megahertz. These terms are commonly used in telecommunications, broadcasting, and electronics industries, where accurate measurements of frequency are crucial for the efficient transmission of data and information.
