This converter allows you to convert technical atmospheres [at] to standard atmospheres [atm] or standard atmospheres [atm] to technical atmospheres [at]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 technical atmosphere [at] ≈ 0.9678 standard atmospheres [atm]1 standard atmosphere [atm] ≈ 1.0332 technical atmospheres [at]

Convert technical atmospheres to standard atmospheres

There are two simple ways to convert technical atmospheres [at] to standard atmospheres [atm]. In the first calculation method, the value in technical atmospheres [at] is divided by the rounded conversion factor of 1.0332. The second method multiplies the value in technical atmospheres [at] by the rounded conversion factor of 0.9678.

  • Standard atmospheres [atm] ≈ technical atmospheres [at] ÷ 1.0332
  • Standard atmospheres [atm] ≈ technical atmospheres [at] * 0.9678

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of technical atmospheres [at] to standard atmospheres [atm] can be achieved using the following calculation method.

  • Standard atmospheres [atm] = technical atmospheres [at] * 98,066.5 ÷ 101,325

Convert standard atmospheres to technical atmospheres

Converting standard atmospheres [atm] to technical atmospheres [at] is easy and can be done in two ways. The first method involves multiplication, in which the value in standard atmospheres [atm] is multiplied by the rounded conversion factor of 1.0332. The second variant is a division. Here, the value in standard atmospheres [atm] is divided by the rounded conversion factor of 0.9678.

  • Technical atmospheres [at] ≈ standard atmospheres [atm] * 1.0332
  • Technical atmospheres [at] ≈ standard atmospheres [atm] ÷ 0.9678

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of standard atmospheres [atm] to technical atmospheres [at] can be achieved using the following calculation method.

  • Technical atmospheres [at] = standard atmospheres [atm] ÷ 98,066.5 * 101,325
