Definition

Noun: 1. A unit of pressure: The barye is the absolute unit of pressure in the centimeter-gram-second (CGS) system of units. It is defined as a pressure of one dyne per square centimeter.

Usage

• The barye is a scientific unit used primarily in physics and engineering contexts within the CGS system.
• It is a very small unit of pressure. For comparison, one standard atmosphere is approximately equal to 1,013,250 barye.
• Example: "The pressure increase in the experiment was measured to be only a few barye."

Advanced Usage

• The barye is also known by the name microbar (µbar), as one barye equals one microbar.
• While largely superseded by the Pascal (Pa) in the International System of Units (SI), the barye is still encountered in some older scientific literature and specific fields like acoustics.
• Example: "In some older acoustics papers, sound pressure levels were given in barye or microbars."

Variants and Related Words

• Microbar (n): Another name for the barye; one microbar equals one dyne per square centimeter.
• Dyne (n): The CGS unit of force. One dyne is the force required to accelerate a mass of one gram at one centimeter per second squared.
• Pascal (n): The SI unit of pressure, equal to one newton per square meter. One pascal is equal to 10 barye.

Synonyms

• Microbar: The direct synonym, used interchangeably with barye.

Notes on Meaning

• The term barye refers specifically to the unit of measurement. It is not to be confused with the word "bar," which is a different, larger unit of pressure (1 bar = 1,000,000 barye).
