- Typing in the Kilopascals field converts back to Bars the same way.
- Use the reference table for the values that come up most often.
Bars to Kilopascals formula
To convert bars to kilopascals, multiply by 100.
kPa = bar × 100
Put another way, one bar is exactly 100 kilopascals.
Why this factor: the bar and the kilopascal are both defined against the pascal, so dividing one definition by the other gives 100 directly. Both definitions are set out in full below.
To go the other way, divide by 100 — or use the Kilopascals to Bars converter, which is the same calculation reversed.
Worked example
Given 32 bar, multiplying by 100 yields 3200 kPa.
32 bar × 100 = 3200 kPa
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 kilopascal?
A kilopascal is 1,000 pascals, the practical metric pressure unit.
Definition: Exactly 1,000 pascals. Standard atmospheric pressure is 101.325 kPa.
Where it is used: Tyre pressures outside the US, weather reports in Canada, and structural engineering loads.
Bars vs Kilopascals
The bar and the kilopascal belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
Frequently asked questions
How many kilopascals are in a bar?
One bar equals 100 kilopascals.
What is the formula to convert bars to kilopascals?
Multiply the number of bars by 100. To reverse it, divide by 100 instead.
How do I convert kilopascals back to bars?
Divide by 100, which is the same as multiplying by 0.01.
How many kilopascals are in 10 bars?
10 bar works out to 1000 kPa.
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.
