🔧 bar to psi Converter
Translate metric gauge pressures into imperial psi.
Perfect for equipment datasheets, automotive specs, and cross-border engineering teams.
3 Bar (bar) equals
43.51132 Pounds per square inch (psi)
SI Reference
Pascals: 300,000 Pa
How to Use This Calculator
Enter bar
Type the metric pressure from gauges, compressors, or hydraulic charts.
Read psi
The converter outputs pounds per square inch with high precision.
Record pascals (optional)
Use the SI reference to plug into formulas or simulation software.
Formula
1 bar = 100,000 Pa
1 psi ≈ 6,894.757 Pa
psi = bar × (100,000 ÷ 6,894.757) ≈ bar × 14.5038
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Many industrial catalogs list pressure ratings in bar, while U.S. equipment and automotive specifications use psi. Accurate conversion keeps teams aligned and prevents underspecifying components.
This calculator uses precise SI factors for reliable results in hydraulic calculations, pneumatic system design, and safety documentation.
Keep the pascal reference handy when interfacing with software packages or standards that expect base SI units.
Frequently Asked Questions
Is bar gauge or absolute?
Bar is often used for gauge and absolute. This converter treats values as absolute; apply offsets if you’re working with gauge pressures.
How many psi are in 1 bar?
Approximately 14.5038 psi. Multiply bar by this factor or use the converter for multi-decimal precision.
Can I convert psi back to bar?
Yes. Divide psi by 14.5038 or use the power converter with the appropriate units.
Does temperature affect the conversion?
Not for unit conversion. Temperature matters when deriving pressure from gas laws, but this tool handles the unit scaling only.
