How to convert kilopascals to bars
To convert a measurement in kilopascals to bars, multiply the value by 0.01. The conversion factor comes from the relationship between both units and the pascal.
For example, to convert 5 kPa to bars: 5 × 0.01 = 0.05 bar.
What is a kilopascal?
A kilopascal equals 1,000 pascals and is the most common metric unit for everyday pressures such as tire inflation. The kilopascal became widespread as metric countries standardized on SI units, replacing older units like the kilogram-force per square centimeter in engineering and automotive specifications.
Common uses of kilopascals include: Tire pressure in metric countries; Blood pressure in some clinical contexts; HVAC and building pressure specifications; Compressed air and pneumatic systems.
What is a bar?
A bar is a metric unit of pressure equal to exactly 100,000 pascals, roughly equal to atmospheric pressure at sea level. Introduced by Norwegian meteorologist Vilhelm Bjerknes, the bar takes its name from the Greek 'baros' (weight). Although not an SI unit, it remains popular in industry, diving, and weather because it is close to one atmosphere.
Common uses of bars include: Scuba diving depth and tank pressure; Industrial hydraulics and pneumatics; European tire and automotive pressure; Weather systems (via millibars).

Frequently asked questions
How many bars are in one kilopascal?
One kilopascal (kPa) equals 0.01 bars (bar). Multiply any value in kilopascals by 0.01 to convert to bars.
How do I convert kilopascals to bars?
Multiply the value in kilopascals by 0.01. For example, 5 kPa × 0.01 = 0.05 bar.
How do I convert bars to kilopascals?
Multiply the value in bars by 100, or divide by 0.01. Use the swap button on the converter above to reverse the direction.
Is the kilopascal to bar conversion exact?
These conversions use standard SI-derived definitions. 1 atm = 101,325 Pa and 1 psi = 6,894.757 Pa exactly by definition.
What is the formula for kilopascals to bars?
The formula is: bar = kPa × 0.01. This comes from the definition of both units relative to the pascal.
