How to convert PSI to bar?

Conversion Formula

To convert PSI to bar, multiply the value in PSI by 0.0689476. This conversion is fundamental for tires, hydraulic systems, and international industrial equipment.

What is PSI?

PSI (Pounds per Square Inch) is a pressure unit in the American imperial system. It represents pounds of force per square inch and is commonly used to measure tire pressure, hydraulic systems, and industrial equipment.

What is a bar?

A bar is a pressure unit in the metric system that equals 100,000 pascals. It is widely used in meteorology, European engineering, and international industrial systems for its practical convenience.

Practical Applications of the Conversion

Automotive Tires

Essential for adjusting tire pressure between American (PSI) and European (bar) standards, international automotive maintenance, and imported vehicle specifications.

Hydraulic Systems

Fundamental for industrial machinery specifications, international hydraulic equipment, and pressure systems that require conversion between American and metric standards.

Industry and Manufacturing

Important for calibrating industrial equipment, international technical specifications, and pressure control systems in global manufacturing plants.

Gases and Compressors

Useful for compressed gas systems, industrial air conditioning equipment, and compressor specifications that operate with different pressure standards.

Frequently Asked Questions

Q What is the exact relationship between PSI and bar?

1 PSI equals exactly 0.0689476 bar. Conversely, 1 bar equals approximately 14.5038 PSI. This conversion is standard in the international industry.

Q Why is this conversion important for tires?

American tires specify pressure in PSI, while European ones use bar. This conversion is essential for international automotive maintenance and vehicle safety.

Q Which pressure is higher: 30 PSI or 2 bar?

30 PSI equals approximately 2.068 bar, so 30 PSI is slightly higher than 2 bar. The difference is about 0.068 bar.
