Definition

1. Noun:
   • A unit of frequency equal to one million hertz (cycles per second): "mc" is an abbreviation for "megacycle," a unit of measurement for frequency, especially in older technical contexts. It is equivalent to one million hertz (1,000,000 Hz) or one megahertz (1 MHz).

Usage

• The abbreviation "mc" is primarily used in technical, scientific, and engineering fields to denote a very high frequency.
• It is considered an older term, largely superseded by the modern SI unit "megahertz" (MHz), which has the same meaning.
• It is typically used with a number to specify a frequency value.

Examples

• Noun:
  • The old radio transmitter operated at a frequency of 1500 mc.
  • The signal was broadcast on the 900 mc band.

Advanced Usage

• The term "mc" can be seen in historical documents, older equipment specifications, and some specialized legacy systems.
• In modern technical writing, "MHz" is the standard and preferred abbreviation.

Variants and Related Words

• Megacycle (n): The full, unabbreviated form of "mc."
• Megahertz (MHz) (n): The modern SI unit equivalent to one million hertz or one megacycle.
• Kilocycle (kc) (n): An older unit for one thousand hertz (kHz).
• Frequency (n): The rate at which a repeating event occurs, measured in hertz (Hz), kilohertz (kHz), megahertz (MHz), etc.

Synonyms

• Megacycle: The full term.
• Megahertz (MHz): The modern equivalent unit.

Notes

• "mc" is an initialism. It is pronounced by saying each letter: "em see."
• Do not confuse this abbreviation with other common abbreviations like "MC," which can stand for "Master of Ceremonies," "Microphone," or "Member of Congress." The meaning is determined entirely by context.
