Convert equivalent pressure measurements across many different units of measure such as pascals to torr, or atmospheres to bar with this pressure conversion table

Pressure is the continuous exertion of physical force by something in direct contact with it. Mathematically it is defined as:

Pressure Calculation

 

 

 

 

 

p is Pressure
F is Force
A is Area

Some common units of measurement this Pressure Conversion chart helps you convert are: atmosphere (atm), bar (b), Dyne (dynes/cm²), hectopascal (hPa), kilogram per sq. cm (kgf/cm²), kilogram per sq. meter (kgf/m²), kilopascal (kPa), millibar (mbar), millimeter of mercury (mmHg), pascal (Pa), pounds per square foot (psf), pounds per square inch (psi), torr (Torr).

Physical Vapor DepositionWhat is PVD Coating?

Physical Vapor Deposition - also known as PVD Coating - refers to a variety of thin film deposition techniques where solid metal is vaporized in a high vacuum environment and deposited on electrically conductive materials as a pure metal or alloy coating. As a process that transfers the coating material on a single atom or molecule level, it can provide extremely pure and high performance coatings which for many applications are much preferable to electroplating.... Read More

 

E-Beam EvaporationWhat is E-Beam Evaporation?

E-Beam or Electron Beam Evaporation is a form of Physical Vapor Deposition in which the target material to be used as a coating is bombarded with an electron beam from a charged tungsten filament to evaporate and convert it to a gaseous state for vapor deposition on the material to be coated. Taking place in a high vacuum chamber, these atoms or molecules in a vapor phase then precipitate and form a thin film coating on the substrate... Read More
