Bar
The bar is a metric pressure unit equal to exactly 100,000 pascals, slightly below one standard atmosphere.
Bars are common in European tire pressure gauges, scuba diving, and industrial compressed-air systems.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 bar = 100 kPa
1 kPa = 0.01 bar
To convert bar to kilopascal, multiply by 100.
To convert kilopascal to bar, multiply by 0.01.
Example: convert 10 bar to kPa
10 × 100 = 1000 kPa
About these units
Short background on the units used in this conversion.
Kilopascal (kPa)
A kilopascal is one thousand pascals — a practical SI scale for everyday and engineering pressures.
Kilopascals label tire pressure in many countries, HVAC ductwork, and meteorological pressure charts.
Frequently asked questions
How many kilopascals are in one bar?
One bar equals 100 kilopascals. Multiply your bars value by 100 to convert to kilopascals.
What is the conversion formula?
kPa = bar × 100The reverse is
bar = kPa × 0.01, using the same exact factors as this converter.Is this Bar to Kilopascal converter private?
