How to Convert KPa to Bar

1 kPa = 0.01 bar exact

Bar = KPa × 0.01

Example: 685 kPa × 0.01 = 6.85 bar

Reverse Conversion

To convert bar back to kPa:

  • Remember, 1 bar equals 100 kPa.
  • To convert 6.85 bar to kPa, multiply 6.85 x 100, resulting in 685 kPa.

exact This conversion factor is exact by international definition.

685 kPa is also equal to:

  • 685000 pascal
  • 99.351 psi
About these units

KPa: SI-derived pressure unit equal to 1,000 pascals (10³ Pa).

Bar: Metric pressure unit equal to exactly 100,000 pascals.
