KPA to BAR Conversion
At Tire Streets, we know that maintaining the correct tire pressure is essential for tire performance, safety, and getting the most out of your setup. Tire pressure can be measured in PSI (pounds per square inch), BAR (bar), and kPa (kilopascal).
While kPa is commonly used in scientific, engineering, and metric pressure measurements, BAR is also widely used in the automotive industry for tire pressure.

Now, let's understand kPa and how to convert kPa to BAR below.
What is kPa?
Kilopascal (kPa) is a metric unit of pressure measurement equal to 1,000 pascals (Pa). The pascal is named after Blaise Pascal, a French scientist who contributed significantly to the study of pressure and hydraulic systems.
kPa is widely used around the world as a unit of pressure and is also commonly found on vehicle tire-pressure specifications.
What is BAR?
BAR is another metric unit used to measure pressure, equivalent to 100,000 pascals.
Although BAR is not an SI (International System of Units) unit, it is widely used for practical pressure measurements, including tire pressure. The simple relationship between kPa and BAR (1 BAR = 100 kPa) makes converting between the two units easy.
What is the Difference Between BAR and kPa?
The difference between BAR and kPa is primarily their scale and how they're commonly used.
1 BAR equals 100 kPa. kPa is an SI-derived metric pressure unit, while BAR is a non-SI metric unit commonly used for applications such as tire pressure.
Both measure pressure, so a tire pressure of 250 kPa is the same as 2.5 BAR.
How to Convert kPa to BAR
1 kPa = 0.01 BAR
The easiest way to convert kPa to BAR is:
BAR = kPa ÷ 100
For example, 220 kPa equals 2.2 BAR:
220 kPa ÷ 100 = 2.2 BAR
If you have a pressure of 230 kPa, the equivalent pressure is 2.3 BAR, while 270 kPa equals 2.7 BAR.
This simple calculation allows you to quickly convert a tire-pressure reading from kPa to BAR.

Frequently Asked Questions About kPa to BAR Conversions
-
Is 1 BAR 100 kPa?
Yes. 1 BAR equals 100 kilopascals (kPa) or 100,000 pascals (Pa).
-
What is the Formula for kPa to BAR?
To convert kPa to BAR, divide the kPa value by 100:
BAR = kPa ÷ 100
For example:
270 kPa ÷ 100 = 2.7 BAR
So, 270 kPa equals 2.7 BAR.
-
How Many BAR is 1,000 kPa?
1,000 kPa equals 10 BAR.
Using the formula:
1,000 kPa ÷ 100 = 10 BAR
-
What is 100 kPa in BAR?
100 kPa equals 1 BAR.
-
What is the Difference Between BAR and kPa?
BAR and kPa are both units used to measure pressure. 1 BAR equals 100 kPa. kPa is an SI-derived metric unit, while BAR is a non-SI metric unit commonly used for practical pressure measurements such as tire pressure.
Maintaining the correct tire pressure is an important part of vehicle maintenance and can affect vehicle safety, tire performance, and efficiency. Whether a pressure is shown in kPa or BAR, knowing the simple conversion between the two makes it easy to understand the correct tire-pressure value.
Tire Streets helps drivers understand tire pressure, sizing, and performance so they can choose and maintain the right tires for the way they drive. Use the kPa to BAR formula and conversion table above whenever you need to quickly translate between the two pressure units.
