About
In automotive maintenance and hydraulic engineering, the Bar is a metric unit of pressure that, while not SI, is legally accepted in the EU and widely used for tire pressure, compressed air systems, and fluid power. Mechanics often encounter gauges calibrated in Kilopascals (kPa) on newer equipment while service manuals specify values in Bar.
This tool provides a rapid, accurate translation between the two. The conversion logic is based on the decimal shift, as 1 bar is defined as exactly 100,000 Pascals (100 kPa). Speed and readability are prioritized here for field use.
Formulas
The conversion is a simple power-of-ten shift:
There are exactly 100 kPa in 1 bar.
