Pressure Converter – Convert PSI, Pascal, Bar, atm, Torr

Our Pressure Converter allows you to convert pressure values between multiple units quickly and accurately. It’s perfect for engineers, scientists, students, and anyone working with pressure measurements.

What is Pressure?

Pressure is the force applied per unit area. It is measured in multiple units such as Pascal (Pa), Bar, PSI, atm, Torr, mmHg, and kPa. Understanding pressure and its conversions is essential for physics, chemistry, and engineering applications.

Common Pressure Units

• Pascal (Pa): SI unit, 1 Pa = 1 N/m²
• Bar: 1 Bar = 100,000 Pa
• PSI (Pounds per Square Inch): Common in engineering, 1 PSI ≈ 6894.76 Pa
• Atmosphere (atm): Standard atmospheric pressure, 1 atm = 101325 Pa
• Torr: 1 Torr ≈ 133.322 Pa
• mmHg: Millimeters of mercury, 1 mmHg ≈ 133.322 Pa
• kPa: Kilopascal, 1 kPa = 1000 Pa

How Our Pressure Converter Works

1. Enter the pressure value you want to convert.
2. Select the input unit (Pa, Bar, PSI, atm, Torr, mmHg, kPa).
3. Select the output unit.
4. Click “Convert” to get the result instantly.

Conversion Formulas

• Pa → Bar: Pa ÷ 100000
• Pa → PSI: Pa ÷ 6894.76
• Pa → atm: Pa ÷ 101325
• Pa → Torr: Pa ÷ 133.322
• Pa → mmHg: Pa ÷ 133.322
• Bar → Pa: Bar × 100000
• PSI → Pa: PSI × 6894.76
• atm → Pa: atm × 101325
• Torr → Pa: Torr × 133.322
• mmHg → Pa: mmHg × 133.322

Example 1 – Pascal to PSI

Convert 50000 Pa to PSI:

50000 ÷ 6894.76 ≈ 7.25 PSI

Example 2 – Bar to atm

Convert 2 Bar to atm:

2 × 100000 = 200000 Pa
200000 ÷ 101325 ≈ 1.97 atm

Example 3 – PSI to kPa

Convert 14.7 PSI to kPa:

14.7 × 6894.76 ≈ 101,352 Pa
101,352 ÷ 1000 ≈ 101.35 kPa

Tips for Using Pressure Converter

• Always note the units before conversion to avoid mistakes.
• Use a calculator for large numbers or multiple conversions.
• Understand standard pressure units in your field of work.
• Combine with other engineering calculators for complete analysis.
• Check significant figures and decimal precision for scientific work.

FAQs – Pressure Converter

Yes, it supports very high or very low values in scientific notation if needed.

Worked Example – Multi-unit Conversion

Convert 3 atm to PSI, Bar, and kPa:

3 atm → Pa: 3 × 101325 = 303,975 Pa
Pa → PSI: 303,975 ÷ 6894.76 ≈ 44.1 PSI
Pa → Bar: 303,975 ÷ 100,000 ≈ 3.04 Bar
Pa → kPa: 303,975 ÷ 1000 ≈ 303.98 kPa
