How to Convert Bars to Pascals
To convert bars to pascals, multiply the pressure by the following conversion ratio: 100,000 pascals/bar.
Since one bar is equal to 100,000 pascals, you can use this simple formula to convert:
The pressure in pascals is equal to the pressure in bars multiplied by 100,000.
For example, here's how to convert 5 bars to pascals using the formula above.
How Many Pascals Are in a Bar?
There are 100,000 pascals in a bar, which is why we use this value in the formula above.
Our bar to pascal calculator automatically converts your pressure measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Bars and pascals are both units used to measure pressure. Keep reading to learn more about each unit.
What Is a Bar?
A bar is a unit of pressure equal to 100,000 pascals (Pa), the base unit for pressure. Metric pressure unit equal to 100,000 Pascals (100 kPa). [1]
The bar is classified as a metric and SI-compatible unit of pressure. Bars can be abbreviated as bar; for example, 1 bar can be written as 1 bar.
When working with bars (bar) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, bars (bar) are widely used across large-scale industrial, bulk, and macro-level pressure specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Pascal?
SI derived unit of pressure equal to 1 Newton per square meter (N/m²). It serves as a primary reference unit for measuring pressure across scientific and practical applications. [2]
The pascal is classified as an International System of Units (SI) unit of pressure. Pascals can be abbreviated as Pa; for example, 1 pascal can be written as 1 Pa.
As the primary coherent reference unit for pressure in this category, all other pressure units are mathematically anchored to the pascal (Pa).
In practice, pascals (Pa) are widely used across standard pressure applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting pressure between bars (bar) and pascals (Pa), keep full floating-point precision (1 bar = 100,000 Pa; 1 Pa = 0.00001 bar) during intermediate calculations and round only the final pascal figure to match your instrument tolerance.
