Technical atmospheres to Bars converter

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

1 at = 0.980665 bar
1 bar ≈ 1.01971621298 at

Formula: bar = at × 0.980665
at ≈ bar × 1.01971621298

Definitions: 1 at = 98066.5 Pa; 1 bar = 100000 Pa

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.

The bar equals exactly 100,000 pascals, which is very close to atmospheric pressure at sea level. It is used for tire and gas pressure in Europe, for scuba tanks (water adds about one bar per 10 meters of depth), and in hydraulics and boilers.
