Convert Bar to Technical Atmosphere (bar to Technical Atmosphere)

Bar (bar) and Technical Atmosphere (Technical Atmosphere) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert bar to technical atmosphere. This free online calculator tool makes it simple and easy to perform the conversion from bar unit to the Technical Atmosphere unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The bar (symbol: bar) is a non-SI unit of pressure equal to exactly 100,000 pascals. It is widely used in meteorology, hydraulic systems, industrial engineering, scuba diving, and tire pressure measurements. Although not an SI unit, the bar is accepted for use with the metric system and remains one of the world's most commonly used pressure units. More information is available in the bar (unit) article.

One bar is equal to 100,000 pascals, 100 kilopascals, 0.1 megapascal, 14.5038 pounds per square inch, and 0.986923 standard atmosphere. The bar provides a convenient pressure scale for engineering and industrial applications.

Technical atmosphere (symbol: at) is a unit of pressure defined as the pressure exerted by one kilogram-force per square centimeter. One technical atmosphere is exactly equal to 98,066.5 pascals, 0.980665 bar, or 0.967841 standard atmosphere (atm). The technical atmosphere was widely used in engineering, hydraulics, and industrial pressure measurements, particularly in Europe, before SI units became the international standard. It is still encountered in older engineering documents and is commonly converted to pascals, bar, and standard atmospheres when interpreting historical specifications and technical data.
