What is Pressure Conversion?

Pressure conversion is the process of converting force-per-area measurements between different units. Pressure is crucial in meteorology, engineering, diving, tire maintenance, and many industrial applications. Different fields use different units - pascals in science, PSI in the US, bar in Europe, and atmospheres for diving. Our pressure converter provides accurate conversions between all common pressure units.

Common Pressure Units Explained

Pascal (Pa)

The SI unit of pressure, equal to one newton per square meter. Used in scientific applications. Atmospheric pressure is about 101,325 Pa.

Bar

Equal to 100,000 pascals. Common in Europe for tire pressure and industrial applications. Roughly equal to atmospheric pressure at sea level.

PSI

Pounds per square inch. Standard in the US for tire pressure, hydraulics, and industrial applications. Normal tire pressure is 30-35 PSI.

Atmosphere (atm)

Based on average sea-level atmospheric pressure. Used in diving, chemistry, and physics. Each 10 meters of water depth adds about 1 atmosphere.

When to Use This Converter

Our pressure converter is essential for drivers checking tire specifications from different countries, divers calculating depth pressure, engineers working with hydraulic systems, meteorologists converting weather data, and scientists working with pressure-sensitive experiments.

Frequently Asked Questions

How do I convert PSI to bar?

Divide PSI by 14.504 to get bar. For example, 30 PSI β‰ˆ 2.07 bar.

What is normal atmospheric pressure?

Standard atmospheric pressure at sea level is 101,325 Pa, 1.01325 bar, 14.696 PSI, or 1 atm. This is used as a reference in many applications.
