Baryes to Pascals (Ba to Pa)
1 barye equals 0.1 pascals exactly.
How to convert baryes to pascals
To convert baryes to pascals, multiply the number of baryes by 0.1. This factor is exact. To go the other way, multiply pascals by 10.
pascals = baryes × 0.1
Example: 10 baryes = 1 pascal.
About these units
Barye (Ba)
Exactly 0.1 pascal, the CGS unit of pressure (one dyne per square centimeter).
Tiny by everyday standards, the barye is the pressure unit of the centimeter-gram-second system. It is one dyne of force spread over one square centimeter, which works out to one gram per centimeter per second squared, or exactly 0.1 pascal. The same quantity has also been called a microbar, and older texts used other spellings and variants such as bary, barad and barrie.
Because of those names the barye is easy to confuse with the bar. In older usage the plain word bar sometimes meant one dyne per square centimeter, particularly in acoustics, a usage now regarded as incorrect. The modern bar is a million baryes, or 100,000 pascals. The barye fits the family of CGS units laid out after the 1873 British Association committee recommended the centimeter, gram and second, and it sits beside the dyne and the erg. It now survives mainly in older physics and acoustics literature. NIST lists the same value as dyne per square centimeter.
1 barye = 0.1 pascals (exactly).

Pascal (Pa)
The SI unit of pressure: one newton per square meter. A very small unit; atmospheric pressure is about 101,325 Pa.
Blaise Pascal never saw a pascal, because the name was adopted by the 14th CGPM in 1971 for the newton per square meter. He did, however, earn the honor. In 1647 he published experiments on the vacuum, and on 19 September 1648 his brother-in-law Florin Périer carried a mercury barometer up the Puy de Dôme near Clermont, where the column stood at about 23 inches against about 26 at the base. Pascal had reasoned that air pressure should fall with altitude, and the result confirmed it.
One pascal is a tiny pressure, so the unit is mostly met with prefixes. Standard atmospheric pressure is 101,325 Pa, a typical sea-level reading is about 1,013 hPa, and the threshold of hearing in air is taken as a reference pressure of 20 micropascals. Building airtightness tests, in contrast, are run at 50 Pa.
Pascal is also remembered for hydrostatics, where he showed that pressure depends on height difference rather than the weight of the fluid, and for the hydraulic press.
The pascal is the reference unit for pressure on this site.
