## What is atmosphere (technical)?

### Definition:

The technical atmosphere is a non-SI unit of pressure equal to 98,066.5 pascals (1 at = 98,066.5 Pa), the SI derived unit of pressure. It is also equal to 980.665 hectopascals (hPa), or 98.0665 kilopascals (kPa), or about 0.967841105 atmospheres (atm), or 0.980665 bars (bar), or 735.55924 millimeters of mercury at 0 °C (mmHg), or 393.7 inches of water at 4 °C (inH2O), or 14.22334 pounds per square inch (psi), or 2,048.16144 pounds per square foot (psf) or 735.55924 torr (Torr).

The technical atmosphere is equal to one kilogram-force per square centimeter (1 at = 1 kgf/cm²). The kilogram-force (kgf) is a non-SI unit of force while the square centimeter (cm²) is a unit of area in the SI.

The technical atmosphere is used in engineering.
