Convert Kilopascal to Bar
Convert kPa to Bar for industrial, diving, and meteorology contexts using the exact 100:1 relationship.
How to Convert Kilopascal to Bar
To convert Kilopascal to Bar, divide kPa by 100 because 1 bar = 100 kPa.
Conversion Formula:
value / 100Understanding the Conversion
Kilopascal to Bar is a simple decimal move—divide by 100. Bar is frequently used in industrial specifications, diving, and some meteorology contexts. Using bar keeps medium-to-high pressures compact: 250 kPa becomes 2.5 bar, 600 kPa becomes 6 bar, and standard atmosphere (101.325 kPa) is about 1.01325 bar.
Choose bar when stakeholders expect it (e.g., compressor datasheets, scuba tank ratings) while keeping SI accuracy in kPa. The conversion is fully reversible: multiply bar by 100 to return to kPa.
Conversion Examples
Example: Convert 250 kPa to bar
- Step 1: 250 ÷ 100 = 2.5.
- Step 2: Result is 2.5 bar.
- Step 3: Straightforward decimal shift.
250 kPa = 2.5 bar
Typical compressor discharge range.
Example: Convert 101.325 kPa to bar
- Step 1: 101.325 ÷ 100 = 1.01325.
- Step 2: Result is 1.01325 bar.
- Step 3: Matches standard atmosphere.
101.325 kPa = 1.01325 bar
Atmospheric reference.
Example: Convert 600 kPa to bar
- Step 1: 600 ÷ 100 = 6.
- Step 2: Result is 6 bar.
- Step 3: Suitable for many industrial systems.
600 kPa = 6 bar
Medium-high system pressure.
Conversion Formula
Bar is defined as 100 kPa. Dividing kPa by 100 moves to bar with a two-place decimal shift.

Unit Definitions
Kilopascal (kPa)
Metric pressure unit.
1 bar = 100 kPa; 1 kPa = 0.01 bar; 1 kPa ≈ 0.145 psi.
Bar (bar)
Metric-adjacent pressure unit common in industry and diving.
1 bar = 100 kPa ≈ 14.5038 psi ≈ 750.062 Torr ≈ 1,000 mbar.
Common Use Cases
- Industrial equipment: convert kPa specs to bar for vendor alignment.
- Diving: relate tank and depth pressures in bar.
- Meteorology: compare to bar-based atmospheric references.
- Hydraulics/pneumatics: present system ratings in bar.
- QA and documentation: include bar for international teams.
Frequently Asked Questions
Is bar an SI unit?
No, but it is widely accepted in industry. SI prefers Pa/kPa.
How close is 1 bar to 1 atm?
1 bar ≈ 0.9869 atm; 1 atm ≈ 1.01325 bar.
Can I go back easily?
Yes. Multiply bar by 100 to get kPa.
