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:

\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.

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

Thus, bar to atm pressure conversion formulas are:

\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:

\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:

\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?

FAQs

### 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.
