To convert bar to pascals (Pa), use this fixed pressure conversion:
This bar to pascal conversion is exact, so you can multiply or divide with confidence.
1 bar equals 100,000 pascals (Pa). This is exact, so you can use it for quick bar to Pa conversions.
Use this formula: Pa = bar × 100,000.
Example: 2.5 bar × 100,000 = 250,000 Pa.
Use this formula: bar = Pa ÷ 100,000.
Example: 300,000 Pa ÷ 100,000 = 3 bar.
The pascal is a small unit. It measures 1 newton per square meter (N/m²). A bar was set as a larger pressure unit close to normal air pressure, so the number of pascals looks big.
The pascal is the SI unit for pressure. The bar is metric-based and widely used, but it is not an SI unit. It stays common in weather, engineering, and pressure gauges.
No. They are close but not equal.
No. These terms refer to different reference points.
1 millibar equals 100 pascals (Pa).
Since 1 bar = 1000 mbar, you can also use: Pa = mbar × 100.
1 kilobar equals 100,000,000 Pa.
That’s because 1 kbar = 1000 bar, and 1 bar = 100,000 Pa.
A pascal measures pressure as force spread over an area.
1 Pa = 1 N/m², which means one newton of force on one square meter.
Use bar for everyday pressure readings like tire pressure, tank pressure, and gauges. Use pascals for science, detailed engineering work, and formulas that expect SI units.
Yes. 1 bar = 100,000 Pa is exact by definition. That makes bar to Pa conversion clean and reliable.
Here are quick reference values:
Pascals can get large fast. Many fields use:
No. The unit conversion never changes. Temperature can change the pressure in a system, but 1 bar will always equal 100,000 Pa.
The Calculate Box tool to convert bars to pascals uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a bars value in the box and have it instantly converted to pascals.
