This converter allows you to convert pascals [Pa] to standard atmospheres [atm] or standard atmospheres [atm] to pascals [Pa]. 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 pascal [Pa] ≈ 9.869 * 10-6 standard atmospheres [atm]1 standard atmosphere [atm] = 101,325 pascals [Pa]

Convert pascals to standard atmospheres

There are two simple ways to convert pascals [Pa] to standard atmospheres [atm]. In the first calculation method, the value in pascals [Pa] is divided by 101,325. The second method multiplies the value in pascals [Pa] by the rounded conversion factor of 9.869 * 10-6.

  • Standard atmospheres [atm] = pascals [Pa] ÷ 101,325
  • Standard atmospheres [atm] ≈ pascals [Pa] * 9.869 * 10-6

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


Convert standard atmospheres to pascals

Converting standard atmospheres [atm] to pascals [Pa] is easy and can be done in two ways. The first method involves multiplication, whereby the value in standard atmospheres [atm] is multiplied by 101,325. The second variant is a division. Here, the value in standard atmospheres [atm] is divided by the rounded conversion factor of 9.869 * 10-6.

  • Pascals [Pa] = standard atmospheres [atm] * 101,325
  • Pascals [Pa] ≈ standard atmospheres [atm] ÷ (9.869 * 10-6)

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