Relation Between Atmosphere (atm) and Bar (bar)
Let me explain to you about the relation between Atmosphere atm and Bar (bar) first before moving to the conversion process. Because it’s essential to grasp what these units represent.What is Atmosphere (atm)?
An atmosphere is a unit of pressure defined as 101,325 pascals. Atmosphere (atm) is a unit of pressure measurement which is commonly used in Atmospheric pressure. Represents the average air pressure at sea level. Commonly used in meteorology and physics. Equivalent to 760 torr or 14.7 psi. Convenient for measuring gases and atmospheric conditions..What is Bar (bar)?
Atmosphere (atm) is another unit of pressure measurement that is used in Industrial pressure. A bar is a unit of pressure equal to 100,000 pascals.. Represents the average air pressure at sea level. Commonly used in meteorology and physics. Equivalent to 760 torr or 14.7 psi. Convenient for measuring gases and atmospheric conditions..How to Convert Bar (bar)?
The conversion between Atmosphere (atm) and Bar (bar) follows a simple formula:Atmosphere = Atmosphere × 1.01325
Where, 1.01325 is the value that allows you to convert between Atmosphere (atm) and Bar (bar).
So,
1 Bar = 1.01325 Atmosphere
And, 1 Atmosphere = 1/1.01325 Bar
Examples of Converting Atmosphere (atm) to Bar (bar)
To convert any value from Atmosphere (atm) to Bar (bar), simply multiply the amount of Atmosphere (atm) by the conversion factor:1 Bar = 1.01325 Atmosphere
For example, if you want to convert 5 Atmosphere into Bar and the conversion factor is 1.01325, then:
5 Atmosphere = 5 x 1.01325 Bar
