Convert PSI to Bar
Convert PSI to Bar for industrial, diving, and compressor contexts using the exact 0.0689476 factor.
How to Convert Psi to Bar
To convert PSI to Bar, multiply psi by 0.0689476.
Conversion Formula:
value * 0.0689476Understanding the Conversion
PSI to Bar is a common Imperial-to-metric conversion for compressors, scuba, and industrial equipment. Multiplying psi by 0.0689476 yields bar. Because bar keeps medium/high pressures readable (e.g., 100 psi ≈ 6.894 bar), it is often preferred on European equipment and diving gauges.
The conversion is linear and reversible. To return to psi, multiply bar by 14.5038.
Conversion Examples
Example: Convert 100 psi to bar
- Step 1: 100 × 0.0689476 = 6.89476.
- Step 2: Result ≈ 6.89 bar.
- Step 3: Typical compressor rating.
100 psi ≈ 6.89 bar
Compressor/industrial reference.
Example: Convert 32 psi to bar
- Step 1: 32 × 0.0689476 ≈ 2.206.
- Step 2: Result ≈ 2.21 bar.
- Step 3: Tire pressure example.
32 psi ≈ 2.21 bar
Passenger tire pressure in bar.
Example: Convert 14.7 psi to bar
- Step 1: 14.7 × 0.0689476 ≈ 1.013.
- Step 2: Result ≈ 1.01 bar.
- Step 3: Atmospheric reference.
14.7 psi ≈ 1.01 bar
Sea-level atmosphere.
Conversion Formula
Bar is about 14.5038 psi. Multiplying psi by 0.0689476 converts to bar; the inverse multiplies bar by 14.5038.

Unit Definitions
Pound per Square Inch (psi)
Imperial pressure unit.
1 psi = 0.0689476 bar = 6.89476 kPa.
Bar (bar)
Metric-adjacent pressure unit.
1 bar = 14.5038 psi = 100 kPa = 1,000 mbar.
Common Use Cases
- Compressors and air tools sold with bar ratings.
- Diving gauges that show bar instead of psi.
- Industrial equipment specs listed in bar.
- QA and documentation requiring both psi and bar.
- Education: demonstrate Imperial-to-metric pressure scaling.
