Megavolt is a unit of measurement for electric potential difference. It is commonly used in fields such as electrical engineering, physics, and chemistry. Synonyms for the word "megavolt" include MV, million volts, and 10^6 volts. In scientific notation, megavolt is expressed as 1 x 10^6 volts or 1,000,000 volts. Other related terms in the field of electricity include kilovolts (1,000 volts), gigavolts (1 billion volts), and teravolts (1 trillion volts). Megavolts are commonly used to measure the voltage of high-power electrical systems, such as those used in power plants, nuclear reactors, and lightning strikes.
