Standard Atmosphere (atm): Defined as 101,325 Pa, approximately the average atmospheric pressure at sea level.
Bar (bar): Metric unit equal to 100,000 Pa, slightly less than atmospheric pressure.
PSI (psi): Pounds per square inch, commonly used in the US and for tire pressure.
Pascal (Pa): SI unit of pressure, equal to one newton per square meter.

Mastering Pressure Conversion: A Complete Guide
Understanding Pressure Units
Pressure is a fundamental physical quantity that measures force per unit area. Different industries and regions use various pressure units, making conversion between them essential for engineers, scientists, meteorologists, and even DIY enthusiasts.
Our pressure converter tool provides real-time conversion between the most commonly used units: atmosphere (atm), bar, pound per square inch (psi), pascal (Pa), and more. With 15+ advanced functionalities, it's designed to be the most comprehensive pressure conversion solution available online.
Key Conversion Formulas
- 1 atm = 101,325 Pa = 1.01325 bar = 14.6959 psi
- 1 bar = 100,000 Pa = 0.986923 atm = 14.5038 psi
- 1 psi = 6,894.76 Pa = 0.068046 atm = 0.0689476 bar
- 1 Pa = 0.00000986923 atm = 0.00001 bar = 0.000145038 psi
