Atmospheres to Technical atmospheres converter

To convert atmospheres to technical atmospheres, enter the value in the first field. The result in technical atmospheres is calculated automatically using the exact conversion factor.

1 atm ≈ 1.0332274528 at
1 at ≈ 0.967841105354 atm

Formula: at ≈ atm × 1.0332274528
atm ≈ at × 0.967841105354

Definitions: 1 atm = 101325 Pa; 1 at = 98066.5 Pa

The standard atmosphere (atm) is exactly 101,325 pascals, the average air pressure at sea level. It is a reference pressure in chemistry and physics and is used to express high pressures as multiples of atmospheric pressure.

The technical atmosphere (at) equals one kilogram-force per square centimeter, exactly 98,066.5 pascals. It is found on older gauges and specifications, especially in the former Soviet Union and older European equipment, and is now largely replaced by the bar.
