Mega

From WikiMD's Food, Medicine & Wellness Encyclopedia

Mega is a term derived from the Greek word megas, meaning "great". In the context of measurement, it is a unit prefix in the metric system denoting a factor of one million (10^6 or 1,000,000). It has the symbol M in the International System of Units (SI).

Usage[edit | edit source]

The prefix mega is widely used in many fields of study such as physics, chemistry, and information technology to denote large quantities. For example, in computing, it is often used to denote multiples of bytes (bytes) in the measurement of data storage capacity (data storage), such as in megabyte (MB) and megabit (Mb).

In Computing[edit | edit source]

In the realm of computing, the term mega is often used to denote 1,048,576 (2^20) bytes, particularly in the context of data storage capacity and data transmission rates, as in megabyte and megabit. However, this usage is inconsistent with the SI definition and has been largely replaced by the binary prefix mebi (Mebi), symbol Mi, denoting 2^20.

In Science and Engineering[edit | edit source]

In science and engineering, mega is used to denote 10^6 of a unit. For example, a megahertz (MHz) is one million hertz (Hz), a megawatt (MW) is one million watts (watt), and a megapascal (MPa) is one million pascals (pascal).

In Popular Culture[edit | edit source]

In popular culture, "mega" is often used informally to denote a large quantity of something or a high degree of something. For example, a "mega event" would be an event of great size or importance.
