1 pascal equals 0.00001 bar.
The pascal and bar both measure pressure, but the pascal is much smaller unit. One bar equals 100,000 pascals, so converting pascal to bar means dividing by 100,000. That’s why 1 pascal is 0.00001 bar.

Conversion Formula
To convert pascal (Pa) to bar, you divide the pascal value by 100,000. This is because 1 bar equals 100,000 pascals exactly. The formula look like this:
Bar = Pascal ÷ 100,000
Since the pascal is a smaller unit of pressure, dividing by 100,000 reduces the number into bars.
Example step-by-step:
- If you have 50,000 pascals, divide 50,000 by 100,000.
- 50,000 ÷ 100,000 = 0.5
- So, 50,000 pascals equals 0.5 bar.
Conversion Example
- Convert 250,000 pascals to bar:
- Divide 250,000 by 100,000.
- 250,000 ÷ 100,000 = 2.5
- The result is 2.5 bar.
- Convert 75 pascals to bar:
- 75 ÷ 100,000 = 0.00075
- So, 75 pascals equals 0.00075 bar.
- Convert 10,000 pascals to bar:
- 10,000 ÷ 100,000 = 0.1
- Therefore it is 0.1 bar.
- Convert 1,000,000 pascals to bar:
- 1,000,000 ÷ 100,000 = 10
- This equals 10 bar.

Conversion Definitions
Pascal: The pascal (Pa) is SI unit for pressure defined as one newton per square meter. It measures force applied over area, commonly used in physics, engineering, and meteorology. This unit is very small, so large pressures often expressed in kilopascals or megapascals.
Bar: A bar is a metric unit of pressure equal exactly to 100,000 pascals. It is used mostly in meteorology and industry for expressing atmospheric pressure and tire pressure. The bar is not an SI unit but accepted for use with SI units.
Conversion FAQs
Why is the pascal such a small unit compared to the bar?
The pascal measures pressure as one newton per square meter, which is a tiny force over area. Since pressure in many applications is much higher, the bar was created to represent 100,000 pascals for convenience, making it easier to communicate larger pressures without large numbers.
Can I convert negative pascal values to bar?
Yes, negative pascal values simply indicate pressures below atmospheric or vacuum pressures. The conversion formula applies the same, dividing by 100,000, so negative pascals become negative bars, maintaining their relative magnitude but in bar units.
Is the bar unit used worldwide?
The bar is widely accepted outside strict SI usage, especially in weather forecasting and industrial settings. Some countries prefer pascals or atmospheres, but the bar remains popular due to its size fitting practical pressure ranges better than pascal alone.
How accurate is converting pascal to bar by division?
The conversion by dividing pascal by 100,000 is exact because the bar is defined as 100,000 pascals exactly. No rounding errors occur unless decimal precision is limited in display or calculation tools.
Are there other pressure units related to pascal and bar?
Yes, units like atmospheres (atm), torr, pounds per square inch (psi), and millibar are used in different fields. Each has its conversion factor to pascal or bar, but pascal and bar remain standard metric units for pressure.
