About Pressure Converter (Pascal, Bar, atm, psi)

The Pressure Converter helps you easily convert between different pressure units including Pascal (Pa), Bar, Atmosphere (atm), and Pounds per Square Inch (psi). It’s a must-use tool for engineers, physics students, and professionals in fluid mechanics, meteorology, and HVAC systems.

Conversion Formulas (Simplified)

1 Bar = 100,000 Pascal (Pa) 1 atm = 101,325 Pascal (Pa) 1 psi = 6,894.76 Pascal (Pa)

These standard conversion ratios help in changing values between common pressure units. For example, 1 atm equals 14.696 psi and 1 bar equals 0.9869 atm.

Example:

Input: Convert 2 atm to psi

Output: 2 atm × 14.696 = 29.392 psi

Steps to Use:

  1. Enter the pressure value you want to convert.
  2. Select the unit you are converting from (Pa, Bar, atm, or psi).
  3. Choose the target unit you want to convert to.
  4. Click 'Calculate' to get the equivalent pressure value.

Frequently Asked Questions

What are the main units of pressure?

The most common units are Pascal (Pa), Bar, Atmosphere (atm), and Pounds per Square Inch (psi). Each is used in different scientific or industrial contexts.

How do I convert between Pascal and Bar?

Divide the Pascal value by 100,000 to get Bar. For example, 200,000 Pa = 2 Bar.

What is the relationship between atm and psi?

1 atmosphere equals approximately 14.696 psi. This conversion is often used in weather, automotive, and fluid system calculations.

Where is this converter useful?

It’s used in laboratories, engineering design, HVAC pressure measurements, meteorology, and automotive tire pressure conversions.

Can I use this calculator for high-pressure systems?

Yes. The tool accurately handles both small-scale (like tire pressure) and large-scale industrial pressure values.
