Handy Units
Bar to kPabar → kPa
1 bar = 100 kPa · 1 kPa = 0.01 bar
Formula
kPa = bar × 100
Example: 2.3 bar = 2.3 × 100 = 230 kPa
These units differ only by a fixed factor: multiply by it to convert, divide to go back. The factors are exact international definitions (for example 1 inch = 2.54 cm exactly); results are rounded only for display.

About these units
Bar (bar)1 bar = 100 kPa, close to one atmosphere; tire pressure is often given in bar.
Kilopascal (kPa)1 kPa = 1,000 Pa. Many car door labels list tire pressure in kPa, such as 250 kPa.
