Convert bar to psi

Bar

A bar is a pressure unit equal to 100,000 pascals.

Bar became widely used in practical pressure measurement because it is close to atmospheric pressure.

bar is used in compressors, pumps, hydraulics, process equipment, diving, mechanical service, and pressure gauges.

Pound per square inch

Pound per square inch is a pressure unit based on one pound-force applied over one square inch.

Psi became common in US customary pressure measurement and remains widely used on gauges and equipment labels.

psi is used for tires, compressors, hydraulics, pneumatics, pressure gauges, industrial equipment, and service documentation.

How to Convert Bar to Pound per square inch

Mathematically, pound per square inch (psi) = bar (bar) converted with the formula below.

1 bar = 14.503774 psi

1 psi = 0.068948 bar

Formula: value × 14.503773773

Example: 15 bar = 217.556607 psi

1. Start with the pressure value in bar.
2. Use 100,000 Pa for each bar.
3. Use 6894.757293168 Pa for each psi.
4. Multiply bar by about 14.503773773 to get psi.

Precision note: Use 1 bar = 14.503773773 psi. Keep precision when values are used for equipment compatibility or safety checks.
