Conversion Formulas
1 bar is a unit of pressure that is not part of the SI system but is widely used in various fields, such as meteorology, engineering, and automotive industries. The exact relation between bar and Pascal is:
1 bar = 100000 Pa (Pascals) = 105 Pascals
Explanation:
The bar is defined as exactly 105 Pa (exactly 100 kilopascals, kPa).
This means 1 bar is equivalent to:
- 1000 hPa (hectopascals (hPa), commonly used in meteorology).
- 0.1 MPa (megapascals (MPa), often used in engineering).
For example:
Standard atmospheric pressure is approximately 1.01325 bar, which is equivalent to 101325 Pa or 101.325 kPa.

Quick Intro to Bar (bar) and its Relation to Other Pressure Units
The bar is a unit of pressure commonly used in various scientific, industrial, and everyday contexts. While not an SI unit, it remains popular due to its practicality and simplicity, particularly in fields such as meteorology, engineering, and automotive applications.
Defined as 1 bar = 100,000 Pa, it provides a straightforward way to express pressure in comparison to the Pascal, the SI unit of pressure.
What Is a Bar?
The bar is defined as a measure of force per unit area, just like the Pascal. However, its larger scale makes it more convenient for certain applications.
For example, atmospheric pressure at sea level is approximately 1.01325 bar, a value close to 1, which simplifies calculations in many contexts. In comparison, expressing this in Pascals results in 101,325 Pa, which can be less intuitive.
The Relationship Between Bar and Pascal (Pa)
The Pascal (Pa) is the SI-derived unit of pressure, defined as 1 Newton per square meter. Since 1 bar = 105 Pa, this means that:
- 1 bar = 100 kilopascals (kPa),
- 1 kPa = 0.01 bar.
This precise relationship allows for easy conversions between the two units, making the bar a practical alternative to Pascals for larger-scale pressure measurements.
Bar and Other Common Pressure Units
Pressure is measured in various units depending on the field of application. Here's how the bar relates to other popular units:
Atmosphere (atm):
- 1 bar ≈ 0.98692 atm.
- Atmospheric pressure at sea level is close to 1 bar, making it easy to approximate in casual discussions.
Pounds per Square Inch (psi):
- 1 bar ≈ 14.5038 psi.
- Psi is widely used in the United States, especially for tire pressure and industrial applications.
Millibar (mbar or hPa):
- 1 bar = 1,000 mbar or 1,000 hPa (hectopascals).
- Meteorologists frequently use millibars to report atmospheric pressure, where standard atmospheric pressure is approximately 1013.25 mbar.
Torr:
- 1 bar ≈ 750.062 Torr.
- Torr is primarily used in vacuum systems and scientific research.
Applications of Bar in Everyday and Industrial Use
The bar’s ease of use makes it a go-to unit for various practical applications:
- Meteorology: Atmospheric pressure readings in weather reports are often expressed in millibars (mbar), a subdivision of bar.
- Engineering: In hydraulic and pneumatic systems, bar is frequently used to measure and describe system pressures.
- Automotive Industry: Tire pressures in many parts of the world are specified in bars, providing a simple way to gauge vehicle performance and safety.
- Scuba Diving: Divers use bar to measure both tank pressure and ambient pressure underwater, ensuring safe and efficient dives.
Why Use Bar?
The bar strikes a balance between accuracy and simplicity. While the Pascal is the scientific standard, its small magnitude often results in cumbersome numbers for practical purposes.
The bar, being a larger unit, reduces the size of these numbers, making it easier to interpret and communicate pressure values.
