Convert bar to kPa
1 bar = 100 kPa · 1 kPa = 0.01 bar · Exact by definition
1 bar = 100 kPa

Digits kept in the answer. Automatic keeps six, which hides floating-point noise without losing anything real.

How the conversion works
kPa = bar × 100
Both units are defined exactly, so the precision of the bar to kPa result depends only on the number of decimal places you choose.
