The barye (symbol: Ba), or sometimes barad, barrie, bary, baryd, baryed, or barie, is the centimetreâÂÂgramâÂÂsecond (CGS) unit of pressure. It is defined as 1 dyne per square centimetre and is equal to 1 microbar. It has also historically been written as "bar", which conflicts with bar.
A barye is also equivalent to 1,000 millibarye or 0.001 kilobarye.
