Bar To Psi Calculator FAQ
Everything you need to know about converting pressure units, understanding Bar and PSI, and tracking your measurements.
To convert Bar to PSI, multiply your pressure value in Bar by 14.5038. For example, if you have 2 Bar, the calculation is 2 × 14.5038 = 29.01 PSI. This calculator automates this process for you instantly.
Bar is a metric unit of pressure defined as exactly 100,000 Pascals (100 kPa). PSI stands for Pounds per Square Inch and is an imperial unit of pressure. While Bar is based on the metric system and widely used globally, PSI is primarily used in the United States and for specific applications like tire pressure in the UK.
1 Bar is exactly equal to 14.5037738 PSI. For most everyday calculations, this is rounded to 14.5 PSI. Atmospheric pressure at sea level is approximately 1.01325 Bar, which is about 14.7 PSI.
The word ‘Bar’ comes from the Greek word ‘barys’, meaning heavy. It is a metric unit of pressure defined as 100,000 Pascals. It was introduced to provide a unit that is close to the atmospheric pressure at sea level, which is approximately 1.01325 Bar.
The Bar unit is widely used in Europe and globally for industrial pressure measurements, weather reporting (often in millibars), scuba diving, and automotive applications. It is preferred in engineering because it avoids the large numbers often seen when using Pascals.
PSI (Pounds per Square Inch) is the standard unit of pressure in the United States and is widely used in the UK and Canada for specific applications. It is most commonly seen for tire pressure, scuba tank pressure, natural gas distribution, and material strength (like tensile strength in steel).
