How to convert pressure

Gauge and absolute pressure use different zero references; changing units does not change that reference. Torr is 1/760 of a standard atmosphere.

Multiply by the source unit factor to get the base quantity, then divide by the target factor. The other-units table compares the same value without retyping it.

A worked example

1 bar = 100000 pascals = 100 kilopascals.

Before you use the result

Displayed values are rounded; extra digits do not make your measurement more accurate. Gauge and absolute pressure use different zero references; changing units does not change that reference. Torr is 1/760 of a standard atmosphere.

bar to kilopascals (kPa): reference values

bar	kilopascals (kPa)
1	100
10	1000
100	10000
