Pressure Converter – Convert Pascal, Bar, PSI, atm & More

Instantly convert between pressure units like pascal (Pa), bar, pounds per square inch (PSI), atmospheres (atm), and torr. Our free pressure conversion tool is perfect for physics, engineering, and weather-related tasks.

What is Pressure? – Definition

Pressure is the force applied perpendicular to the surface of an object per unit area. It helps describe how much force is exerted over a surface.

A car tire may be inflated to 32 PSI, while atmospheric pressure at sea level is about 101,325 Pascals. This shows how pressure values vary in different situations.

Commonly Used Pressure Units

• Pascal (Pa) – SI unit of pressure
• Bar – 1 bar = 100,000 Pa
• Pounds per square inch (PSI) – Common in the US
• Atmosphere (atm) – Standard atmospheric pressure
• Torr – 1 atm = 760 torr
• Millimeter of mercury (mmHg) – Used in medicine and weather
