This converter allows you to convert technical atmospheres [at] to millibar [mbar] or millibar [mbar] 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] = 980.665 millibar [mbar]1 millibar [mbar] ≈ 0.001 technical atmospheres [at]

Convert technical atmospheres to millibar

There are two simple ways to convert technical atmospheres [at] to millibar [mbar]. In the first calculation method, the value in technical atmospheres [at] is divided by the rounded conversion factor of 0.001. The second method multiplies the value in technical atmospheres [at] by 980.665.

  • Millibar [mbar] ≈ technical atmospheres [at] ÷ 0.001
  • Millibar [mbar] = technical atmospheres [at] * 980.665

The calculation method with a rounded conversion value is more suitable for rough conversions from technical atmospheres [at] to millibar [mbar], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert millibar to technical atmospheres

Converting millibar [mbar] to technical atmospheres [at] is easy and can be done in two ways. The first method involves multiplication, in which the value in millibar [mbar] is multiplied by the rounded conversion factor of 0.001. The second variant is a division. Here, the value in millibar [mbar] is divided by 980.665.

  • Technical atmospheres [at] ≈ millibar [mbar] * 0.001
  • Technical atmospheres [at] = millibar [mbar] ÷ 980.665

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from millibar [mbar] to technical atmospheres [at] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
