This converter allows you to convert megabar [Mbar] to standard atmospheres [atm] or standard atmospheres [atm] to megabar [Mbar]. 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 megabar [Mbar] ≈ 986,923.2667 standard atmospheres [atm]1 standard atmosphere [atm] ≈ 1.013 * 10-6 megabar [Mbar]

Convert megabar to standard atmospheres

There are two simple ways to convert megabar [Mbar] to standard atmospheres [atm]. In the first calculation method, the value in megabar [Mbar] is divided by the rounded conversion factor of 1.013 * 10-6. The second method multiplies the value in megabar [Mbar] by the rounded conversion factor of 986,923.2667.

  • Standard atmospheres [atm] ≈ megabar [Mbar] ÷ (1.013 * 10-6)
  • Standard atmospheres [atm] ≈ megabar [Mbar] * 986,923.2667

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

  • Standard atmospheres [atm] = megabar [Mbar] ÷ 101,325 * 1011

Convert standard atmospheres to megabar

Converting standard atmospheres [atm] to megabar [Mbar] 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 1.013 * 10-6. The second variant is a division. Here, the value in standard atmospheres [atm] is divided by the rounded conversion factor of 986,923.2667.

  • Megabar [Mbar] ≈ standard atmospheres [atm] * 1.013 * 10-6
  • Megabar [Mbar] ≈ standard atmospheres [atm] ÷ 986,923.2667

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 megabar [Mbar] can be achieved using the following calculation method.

  • Megabar [Mbar] = standard atmospheres [atm] * 101,325 ÷ 1011
