Definition:Barye

Definition

The barye is the CGS unit of pressure.

It is defined as being:

The amount of pressure required to apply a force of $1$ dyne over an area of $1$ square centimetre.

Symbol

$\mathrm {Ba}$

The symbol for the barye is $\mathrm {Ba}$.

Its $\LaTeX$ code is \mathrm {Ba} .

Base Units

The CGS base units of the barye are:

$\mathrm {Ba} := \mathrm {g \, cm^{-1} \, s^{-2} }$

where:

$\mathrm g$ denotes grams

$\mathrm {cm}$ denotes centimetres

$\mathrm s$ denotes seconds (of time).

Also known as

The term barye can be seen in various forms:

• barad
• barrie
• bary
• baryd
• baryed
• barie

The term barye in the context of a unit of pressure is in fact relatively new.

Hence older works will generally use the term dyne per square centimetre.

Linguistic Note

The word barye originates from the $19$th century French, and ultimately derives from Greek barus, meaning heavy.

It is pronounced bar-ry, that is, rhyming completely with the word carry.
