Convert Technical Atmosphere to Kilopascal (at to Kilopascal)

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

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.

The kilopascal (symbol: kPa) is an SI-derived unit of pressure equal to one thousand (10³) pascals. It is one of the most widely used pressure units in engineering, meteorology, automotive systems, construction, and scientific research. The kilopascal provides a practical scale for measuring atmospheric pressure, tire pressure, and fluid pressure. It uses the SI prefix kilo, representing a factor of one thousand.

One kilopascal is equal to 1,000 pascals, 0.01 bar, 0.001 megapascal, 0.145038 psi, and 0.00986923 standard atmosphere. The kilopascal is the preferred SI unit for many everyday and industrial pressure measurements.
