1 bar equals 100 kPa. To convert bar to kPa, multiply the value by 100; divide by 100 to convert back. Enter any number above and the result appears instantly — free and entirely in your browser.
How do you convert bar to kPa?
The conversion formula is kPa = bar × 100. The conversion factor is fixed by definition, so the result is always exact.

What is bar (bar)?
The bar is a metric pressure unit equal to exactly 100,000 pascals — very close to average air pressure at sea level. It is widely used across Europe for tyre pressure, weather reports and industrial systems.
What is kPa (kPa)?
The kilopascal (kPa) equals 1,000 pascals and is the SI-based unit most used in science, engineering and many vehicle manuals outside the United States.
Why convert bar to kPa?
Pressure units differ by region and field: Europe uses bar, the US uses psi, science uses pascals and kilopascals, and medicine still uses mmHg. Converting between them is a daily need for mechanics, engineers and divers.
Standard atmospheric pressure is defined as exactly 101,325 Pa — equal to 1.01325 bar or 14.696 psi (BIPM/NIST). Car tyres are typically inflated to about 2.2–2.5 bar (32–36 psi).
