How to Convert atm to Bar?
Converting from atm to Bar is a straightforward process. Follow these steps to ensure accurate conversions from standard atmosphere to bar:
- Select the Standard Atmosphere Value: Start by determining the standard atmosphere (atm) value you want to convert into bar (Bar). This is your starting point.
- Multiply by the Conversion Factor: To calculate standard atmosphere to equivalent bar amount, multiply the selected atm value by 1.01325.
- Illustration of Multiplication:
- 1 atm = 1.01325 Bar
- 10 atm = 10.1325 Bar
- 100 atm = 101.325 Bar
- Find the Conversion Result: The result of this multiplication is your converted value in bar unit. This represents the same pressure but in a different unit.
- Save Your Bar Value: After converting, remember to save the result. This value represents the pressure you initially measured, now expressed in bars.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the standard atmosphere value by 0.986923266716. This alternative method also gives you the correct pressure in bars.
- Illustration of Division:
- Bar = atm ÷ 0.986923266716
What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Standard Atmosphere?
The standard atmosphere (symbol: atm) is a non-SI unit of pressure defined as exactly 101,325 pascals. It represents the average atmospheric pressure at sea level under standard conditions and is widely used in chemistry, physics, meteorology, and engineering. The standard atmosphere provides a convenient reference for pressure measurements and scientific calculations. Additional information is available in the standard atmosphere reference.
One standard atmosphere is equal to 101,325 pascals, 1.01325 bars, 101.325 kilopascals, 14.6959 pounds per square inch, and 760 millimeters of mercury. The standard atmosphere is one of the most important reference units in science and engineering.
What is Bar?
The bar (symbol: bar) is a non-SI unit of pressure equal to exactly 100,000 pascals. It is widely used in meteorology, hydraulic systems, industrial engineering, scuba diving, and tire pressure measurements. Although not an SI unit, the bar is accepted for use with the metric system and remains one of the world's most commonly used pressure units. More information is available in the bar (unit) article.
One bar is equal to 100,000 pascals, 100 kilopascals, 0.1 megapascal, 14.5038 pounds per square inch, and 0.986923 standard atmosphere. The bar provides a convenient pressure scale for engineering and industrial applications.

Standard Atmosphere to Bar Examples
Example 1:
Convert 0.2 Standard Atmosphere pressure to Bar unit.
Solution:
We know that one Standard Atmosphere is equivalent to 1.01325 Bar.
Therefore,
0.2 atm = 0.2 x 1.01325 Bar.
0.2 atm = 0.20265 Bar.
Hence, 0.2 Standard Atmosphere is approximately equal to 0.20265 Bar.
Example 2:
Convert 8 Standard Atmosphere pressure to Bar unit.
Solution:
We know that one Standard Atmosphere is equivalent to 1.01325 Bar.
Therefore,
8 atm = 8 x 1.01325 Bar.
8 atm = 8.106 Bar.
Hence, 8 Standard Atmosphere is approximately equal to 8.106 Bar.
