About this calculator

Bar and kilopascal are both metric pressure units, related by an exact factor of 100 (since 1 bar = 100,000 pascals = 100 kPa exactly). This calculator performs that conversion instantly, useful when working with process engineering data sheets that use kPa instead of bar.

Formula

kPa = bar × 100
  • barPressure — bar
  • kPaPressure — kilopascals

Worked Example

Given: A pressure gauge reads 7 bar.

Result: 7 × 100 = 700 kPa.

How to Use

  1. Enter the pressure in bar.
  2. Click Calculate to see the value in kPa.

Important Assumptions

  • This is an exact conversion with no rounding error.

Common Mistakes

  • Confusing kPa with MPa (1 MPa = 1000 kPa = 10 bar).

Frequently Asked Questions

Is the bar-to-kPa conversion always exact?

Yes — 1 bar is defined as exactly 100,000 pascals, so the factor of 100 to kPa has no rounding error.
