Do a quick bar to atm conversion using our intuitive tool. This bar to atm converter will help to convert pressure (or stress) in bars to atmospheres (atm) or vice versa. And that's not all: you can even use it to convert pressure to other units! Read the following article to learn about the units of pressure, such as bar and atm, and how to convert from bars to atm.

Bar to atm conversion

Bar is a unit of pressure that does not belong to the International System of Units (SI) and is equal to:

1 bar=0.986923 atm=105 Pa=100 kPa\begin{align*} \rm 1 \text{ } bar &= \rm 0.986923\text{ } atm \\ \rm &= \rm 10^5\text{ } Pa \\ \rm &=\rm 100 \text{ } kPa \end{align*}

Standard atmosphere (atm) is a unit of pressure equal to 101,325 Pa. It is approximately equal to the average atmospheric pressure on Earth at sea level.

1 atm=101, ⁣325 Pa\rm 1 \text{ } atm = \rm 101,\!325\text{ } Pa

Thus, bar to atm pressure conversion formulas are:

 atm= bar value×0.986923 bars= atm value×1.01325\begin{align*} \rm \text{ }atm &= \rm \text{ }bar \ value \times 0.986923 \\ \rm \text{ }bars &=\rm \text{ }atm \ value \times 1.01325 \end{align*}

How to convert bar to atm?

Let's say the pressure is 3 bar, hence we can easily do the conversion of bar to atm:

3 bar=3×0.986923=2.96077 atm\begin{align*} \rm 3 \text{ } bar &= \rm 3 \times 0.986923 \\ \rm &=\rm 2.96077 \text{ }atm \end{align*}

Now let's see how to convert 5 atm to bars using the above formulas:

5 atm=5×1.01325=5.06625 bar\begin{align*} \rm 5 \text{ } atm &= \rm 5 \times 1.01325 \\ \rm &=\rm 5.06625 \text{ }bar \end{align*}

How to use this bar to atm conversion tool?

Using our bar to atm converter is really intuitive, just:

  1. Enter the pressure in bars, and our tool instantly converts bar to atm.

  2. Specify the pressure in atm, and our tool will automatically perform the atm to bar pressure conversion.

  3. Any other pressure/stress unit is welcome! Click the unit label in any field, and you will see a list of units to choose from.

How many bars are present in 1 atm?

1 atm is equal to 1.01325 bars. Atm stands for mean atmospheric pressure at sea level and is 101,325 Pa or 101.325 kPa. In turn, 1 bar is equivalent to 100,000 Pa or 100 kPa. Hence, the standard atmospheric pressure is 1.01325 bar.

How can I convert 12 bars to atm?

To do it:

  1. Find the unit conversion rate from bars to hectopascals:
    0.986923 bar = 1 atm.

  2. Multiply 12 bars by 0.986923:
    0.986923 × 12 bar = 11.843 atm.

  3. Compare your result with our bar to atm conversion tool.
