How to use
- Enter a value in the Bars field.
- The Pascals figure appears immediately — no button to press.
- Typing in the Pascals field converts back to Bars the same way.
- Use the reference table for the values that come up most often.
Bars to Pascals formula
To convert bars to pascals, multiply by 100000.
Pa = bar × 100000
Put another way, one bar is exactly 100,000 pascals.
Why this factor: the bar and the pascal are both defined against the pascal, so dividing one definition by the other gives 100000 directly. Both definitions are set out in full below.
To go the other way, divide by 100000 — or use the Pascals to Bars converter, which is the same calculation reversed.
Worked example
Take 760 bar and multiply by the factor 100000: the result is 76000000 Pa.
760 bar × 100000 = 76000000 Pa
The converter above does this for any value you type, in either direction.
What is a bar?
A bar is a metric pressure unit chosen to sit very close to atmospheric pressure.
Definition: Exactly 100,000 pascals by definition. Standard atmosphere is 1.01325 bar, so a bar is slightly less.
Where it is used: European tire and hydraulic pressures, diving depth equivalents, and espresso machine ratings.
Worth knowing: Close to one atmosphere but not equal to it — the difference is about 1.3%.
What is a pascal?
The pascal is the SI unit of pressure — one newton of force spread over one square meter.
Definition: Defined as 1 N/m². Named after Blaise Pascal.
Where it is used: Scientific and engineering pressure calculations, and weather pressure in hectopascals.
Worth knowing: A single pascal is a very small pressure, which is why weather reports use hectopascals and engineering uses kilopascals.
Bars vs Pascals
The bar is a metric unit while the pascal is an SI unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
Frequently asked questions
How many pascals are in a bar?
One bar equals 100000 pascals.
What is the formula to convert bars to pascals?
Multiply the number of bars by 100000. To reverse it, divide by 100000 instead.
How do I convert pascals back to bars?
Divide by 100000, which is the same as multiplying by 1e-05.
How many pascals are in 10 bars?
10 bar works out to 1000000 Pa.
Is there anything to watch out for with bars?
Close to one atmosphere but not equal to it — the difference is about 1.3%.
How is the bar defined?
Exactly 100,000 pascals by definition. Standard atmosphere is 1.01325 bar, so a bar is slightly less.
